Detailed Description

Option constants /

Variable Documentation

HAVE_ATOMIC_OPERATIONS

const Qore::Option::HAVE_ATOMIC_OPERATIONS = bool(QORE_CONST_HAVE_ATOMIC_MACROS)

Indicates if the Qore library supports fast atomic reference counting.

Note that if this constant is False, atomic operations are supported by mutexes and are therefore slower than with native atomic reference counting operations

HAVE_FILE_LOCKING

const Qore::Option::HAVE_FILE_LOCKING = bool(QORE_CONST_HAVE_STRUCT_FLOCK)

Indicates if the Qore library supports file locking; currently this depends on UNIX-style file locking with the fnctl() function.

Note

Currently this function is only available when running on UNIX or UNIX-like platforms

HAVE_FORK

const Qore::Option::HAVE_FORK = bool(QORE_CONST_HAVE_FORK)

Indicates if the fork() function is available.

Note

This constant is always False on native Windows ports

HAVE_GET_NETIF_LIST

const Qore::Option::HAVE_GET_NETIF_LIST = bool(QORE_CONST_HAVE_GET_NETIF_LIST)

Indicates if the get_netif_list() function is available.

Since

Qore 0.9.0

HAVE_GET_STACK_SIZE

const Qore::Option::HAVE_GET_STACK_SIZE = bool(QORE_CONST_HAVE_GET_STACK_SIZE)

Indicates if the get_stack_size() function is available.

Since

Qore 0.9.0

HAVE_GETPPID

const Qore::Option::HAVE_GETPPID = bool(QORE_CONST_HAVE_GETPPID)

Indicates if the getppid() function is available.

Note

This constant is always False on native Windows ports

HAVE_IS_EXECUTABLE

const Qore::Option::HAVE_IS_EXECUTABLE = bool(QORE_CONST_HAVE_PWD_H)

Indicates if the Qore library supports the is_executable() function.

Note

Currently this function is only available when running on UNIX or UNIX-like platforms

HAVE_KILL

const Qore::Option::HAVE_KILL = bool(QORE_CONST_HAVE_KILL)

Indicates if the kill() function is available.

Since

Qore 0.9 always True

HAVE_SETEGID

const Qore::Option::HAVE_SETEGID = bool(QORE_CONST_HAVE_SETEGID)

Indicates if the setegid() function is available; the availabilty of this function depends on the system's underlying C-library.

HAVE_SIGNAL_HANDLING

const Qore::Option::HAVE_SIGNAL_HANDLING = qore((bool)(QORE_CONST_HAVE_SIGNAL_HANDLING && !(qore_library_options & QLO_DISABLE_SIGNAL_HANDLING)))

Indicates if UNIX-style signal handling is available.

If this constant is False, then the set_signal_handler() and remove_signal_handler() functions are not available.
