(

)

Deletes all keys in the thread-local data hash.

Restrictions:

Qore::PO_NO_THREAD_CONTROL

Example:

delete_all_thread_data();

Note

This function does not throw any exceptions, however if an object is deleted from the thread-local data hash, then it could throw an exception in its destructor

delete_thread_data() [1/2]

(

)

Returns the entire thread-local data hash.

Returns

the entire thread-local data hash

Restrictions:

Qore::PO_NO_THREAD_CONTROL, Qore::PO_NO_THREAD_INFO

Code Flags:

RET_VALUE_ONLY

Example:

hash<auto> th = get_all_thread_data();

Note

this function is not flagged with CONSTANT since its value could change at runtime

get_default_thread_stack_size()

int Qore::get_default_thread_stack_size

(

)

returns the default thread stack size

Platform Availability:

Qore::Option::HAVE_MANAGE_STACK

Restrictions:

Qore::PO_NO_THREAD_INFO

Code Flags:

CONSTANT

Example:

Qore 0.8.13

throw_thread_resource_exceptions()

nothing Qore::throw_thread_resource_exceptions

(

)

Immediately runs all thread resource cleanup routines for the current thread and throws all associated exceptions.

This function is particularly useful when used in combination with embedded code in order to catch (and log, for example) thread resource errors (ex: uncommitted transactions, unlocked locks, etc) - this can be used when control returns to the "master" program to ensure that no thread-local resources have been left active.

This function will run all thread resource cleanup routines even if mark_thread_resources() has been called (i.e. it clears all marks as well).

When exceptions are thrown by this function, thread-local resources are also cleaned up at the same time.

Restrictions:

Qore::PO_NO_THREAD_CONTROL

Example:

try {
    throw_thread_resource_exceptions();
} catch (hash<ExceptionInfo> ex) {
    # ... log or handle exceptions
}

Note

may not throw an exception even if there are thread resources in place that get cleaned up in case the Qore::Thread::AbstractThreadResource::cleanup() method performs the cleanup but does not throw an exception

See also

• mark_thread_resources()
• remove_thread_resource()

throw_thread_resource_exceptions_to_mark()

bool Qore::throw_thread_resource_exceptions_to_mark

(

)

Immediately runs all thread resource cleanup routines for the current thread for thread resources created since the last call to mark_thread_resources() and throws all associated exceptions.

When exceptions are thrown by this function, thread-local resources are also cleaned up at the same time.

Returns

True if there are additional thread resource marks to process, False if there are no more

Restrictions:

Qore::PO_NO_THREAD_CONTROL

Example:

try {
    mark_thread_resources();
    # ... some code or calls that may allocate thread resources
 
    # calling the following will ensure that any thread-resources allocated since
