Macro Definition Documentation

◆ MAX_AUTO_THREADS

#define MAX_AUTO_THREADS 16

Definition at line 26 of file pthread_internal.h.

◆ THREAD_SENTINEL

#define THREAD_SENTINEL 0

Definition at line 34 of file pthread_internal.h.

◆ OFFSET_ARRAY

#define OFFSET_ARRAY ( ... ) __VA_ARGS__, THREAD_SENTINEL

Macros to help creating the above lists.

mutexes and conds need to be parentheses-enclosed lists of offsets in the containing structure.

Definition at line 60 of file pthread_internal.h.

◆ DEFINE_OFFSET_ARRAY

#define DEFINE_OFFSET_ARRAY	(	type,
		name,
		cnt_variable,
		mutexes,
		conds
	)

Value:

static const unsigned name ## _offsets[] = { offsetof(type, cnt_variable),    \
                                             OFFSET_ARRAY mutexes,            \
                                             OFFSET_ARRAY conds }

◆ ff_pthread_init()

int ff_pthread_init	(	void *	obj,
		const unsigned	offsets[]
	)

Initialize/destroy a list of mutexes/conditions contained in a structure.

The positions of these mutexes/conditions in the structure are given by their offsets. Because it is undefined behaviour to destroy an uninitialized mutex/condition, ff_pthread_init() stores the number of successfully initialized mutexes and conditions in the object itself and ff_pthread_free() uses this number to destroy exactly the mutexes and condition variables that have been successfully initialized.

Parameters

	obj	The object containing the mutexes/conditions.
[in]	offsets	An array of offsets. Its first member gives the offset of the variable that contains the count of successfully initialized mutexes/condition variables; said variable must be an unsigned int. Two arrays of offsets, each delimited by a THREAD_SENTINEL follow. The first contains the offsets of all the mutexes, the second contains the offsets of all the condition variables.
