string

path

)

Returns a string giving the path up to a file but not the filename itself.

Code Flags:

CONSTANT

Parameters

path	the path to process

Returns

a string giving the path up to a file but not the filename itself; if no directory separator characters can be found in the path, "." is returned (meaning the current directory)

basename()

errno()

int Qore::errno

(

)

Returns the error code of the last error that occurred in the current thread.

Restrictions:

Qore::PO_NO_PROCESS_CONTROL

Parameters

rc	the return code for the process (0 = no error; success)

Example:

exit(0);

See also

abort()

fork()

int Qore::fork

(

)

Creates a copy of the current process with a new PID; returns 0 in the child process; returns the child's PID in the parent process.

This function will throw an ILLEGAL-FORK exception if more than one thread is running

Platform Availability:

Qore::Option::HAVE_FORK

Restrictions:

Qore::PO_NO_PROCESS_CONTROL

Returns

0 in the child process; returns the child's PID in the parent process; if an error occurs, then -1 is returned, in this case no child process was started and the error number can be retrieved with the errno() function

Example:

int pid;
if (pid = fork())
    printf("child has PID %d\n", pid);

Exceptions

ILLEGAL-FORK

Cannot fork if more than one thread is running

Note

• after a fork(), the only safe call is exec(), many system calls are not async-signal safe, including pthread_create() which is used to start new threads.
• the Qore process will crash if unsafe operations are called after a fork()
• the signal-handling thread cannot be reliably started on many platforms (ex: FreeBSD) after a fork(), therefore signal handling is disabled in the child process after a fork()
• on Darwin (OS/X) threading primitives are unusable in the child process after a fork()

Parameters

pid

the pid argument can have the following interpretations: > 0: the signal is sent to the process ID given 0: the signal is sent to all processes whose group ID is equal to the process group ID of the sender, and for which the process has permission -1: if the user has super-user privileges, the signal is sent to all processes excluding system processes and the process sending the signal. If the user is not the super user, the signal is sent to all processes with the same uid as the user, excluding the process sending the signal. No error is returned if any process could be signaled.

sig

the signal number to send to the process or processes

Returns

0 means success (no error), or -1 meaning an error occurred; in this case check errno() for the error

srand() [1/2]

nothing Qore::srand

(

)

This function variant does nothing at all; it is only included for backwards-compatibility with qore prior to version 0.8.0 for functions that would ignore type errors in arguments.

Restrictions:

Qore::PO_NO_PROCESS_CONTROL

Code Flags:

RUNTIME_NOOP

srand() [2/2]

nothing Qore::srand

(

softint

seed

)

Seeds the random number generator with the integer passed.

This function uses the C library function srandom() if available on the current platform, otherwise uses srand()

Restrictions:

Qore::PO_NO_PROCESS_CONTROL

Parameters

seed	the seed for the random number generator (only the least-significant 32-bits are used)

Example:

srand(now());

See also

rand() for a function that returns a random number related to the seed given here

Since

Qore 0.8.13 the random number generator is seeded randomly when the Qore library is initialized

stat() [1/2]

nothing Qore::stat

(

)

This function variant does nothing at all; it is only included for backwards-compatibility with qore prior to version 0.8.0 for functions that would ignore type errors in arguments.

Qore::PO_NO_FILESYSTEM

Code Flags:

RUNTIME_NOOP

stat() [2/2]

*list<auto> Qore::stat

(

string

path

)

Returns a list of file status values for the path argument, following any symbolic links; if any errors occur, NOTHING is returned and errno() can be used to retrieve the error number.

Restrictions:

Qore::PO_NO_FILESYSTEM

Parameters

path	the path to retrieve information for

Returns

a list of file status values for the path argument, following any symbolic links; if any errors occur, NOTHING is returned and errno() can be used to retrieve the error number

Example:

*list<auto> l = stat("/tmp/file.txt");
if (!exists l)
    printf("could not stat /tmp/file.txt: %s\n", strerror());

See also

lstat() for a version of this function that does not follow symbolic links

hstat() for a version of this function that returns a user-friendly hash instead of a list

File::stat() for a static method in the File class that throws an exception instead of returning NOTHING when errors occur

statvfs()

*hash<FilesystemInfo> Qore::statvfs

(

string

path

)

Returns a hash of filesystem status values for the file or directory path passed.

Platform Availability:

Qore::Option::HAVE_STATVFS

Restrictions:

Qore::PO_NO_FILESYSTEM

Parameters

path	the path to the filesystem (or on the filesystem)

Returns

a FilesystemInfo hash; or, if any errors occur, NOTHING is returned and errno() can be used to retrieve the error number

Example:

*hash<FilesystemInfo> h = statvfs("/tmp")

See also

File::statvfs() for a static method in the File class that throws an exception instead of returning NOTHING when errors occur

strerror() [1/2]

string Qore::strerror

(

)

Returns the string corresponding to the last error that occurred in the current thread.

Returns

the string corresponding to the last error that occurred in the current thread

Code Flags:

CONSTANT

Example:

if (unlink(path))
    printf("%s: %s\n", path, strerror());

Since

Qore 0.8.4 this variant of the function automatically uses the last error value for the current thread

strerror() [2/2]

string Qore::strerror

(

softint

err

)

Returns the string corresponding to the error code passed (generally retrieved with errno())

Code Flags:

CONSTANT

Parameters

err	the error code to retrieve the description for (generally provided by errno())

Returns

the string corresponding to the error code passed; if the error code is unknown, then a string like "Unknown error: -1" is returned

Example:

if (unlink(path))
    printf("%s: %s\n", path, strerror(errno()));

symlink()

nothing Qore::symlink	(	string	old_path,
		string	new_path
	)

Creates a symbolic link to a directory path. Note that for this call to function properly, the Qore process must have sufficient permissions and access to the given filesystem path to create the symbolic link.

Platform Availability:

Qore::Option::HAVE_UNIX_FILEMGT

Restrictions:

Qore::PO_NO_FILESYSTEM

This function does not return any value; if any errors occur, an exception is thrown. If the target of the symbolic link does not exist, it is not an error; the symbolic link is created anyway.

Parameters

old_path	The original path; the target of the link
new_path	The path to the location of the new symbolic link to be created with this function call

Example:

symlink("/tmp/temporary-dir", "/users/oracle/install");

Exceptions

SYMLINK-ERROR

empty string passed for one of the arguments or the operating system returned an error

Since

Qore 0.8.5

system() [1/2]

nothing Qore::system

(

)

This function variant does nothing at all; it is only included for backwards-compatibility with qore prior to version 0.8.0 for functions that would ignore type errors in arguments.

Restrictions:

Qore::PO_NO_EXTERNAL_PROCESS

Code Flags:

RUNTIME_NOOP

system() [2/2]

int Qore::system

(

string

command

)

executes a command and returns the exit code of the process

Platform Availability:

Qore::Option::HAVE_SYSTEM

Restrictions:

Qore::PO_NO_EXTERNAL_PROCESS

Parameters

command

the command to execute with system() (3)

Returns

the exit code of the process executed

Example:

int rc = system("ls -l");

Code Flags:

RUNTIME_NOOP

umask() [2/2]

int Qore::umask

(

softint

mask

)

)

Deletes a file and returns 0 for success, -1 for error (in which case errno() can be used to get the error)

Does not delete directories; see rmdir() for a similar function that removes directories

Restrictions:

Qore::PO_NO_FILESYSTEM

Parameters

path	the path to the file to delete

Returns

0 for success, -1 for error (in which case errno() can be used to get the error)

int Qore::usleep

(

date

d

)

Causes the current thread to sleep for a certain number of microseconds.

Restrictions:

Qore::PO_NO_PROCESS_CONTROL

Parameters

d	A time value giving the amount of time in microseconds to sleep; this should be a relative date/time value to make the source more readable (ex: 250ms)

Returns

should always return 0 for success

Example:

usleep(250ms);

See also

sleep() for a similar function supporting second resolution

Note

both sleep() and usleep() are implemented internally by calls to nanosleep() (2) if available on the current platform, otherwise both are implemented by calls to usleep() (3)

(

softint

usecs

)

Causes the current thread to sleep for a certain number of microseconds.

Restrictions:
