Private Support Information for POSIX Threads.

Macro Definition Documentation

PTHREAD_MINIMUM_STACK_SIZE

#define PTHREAD_MINIMUM_STACK_SIZE   _POSIX_Threads_Minimum_stack_size

The following sets the minimum stack size for POSIX threads.

Function Documentation

_POSIX_Thread_Translate_sched_param()

int _POSIX_Thread_Translate_sched_param	(	int	policy,
		const struct sched_param *	param,
		Thread_Configuration *	config
	)

Translates the POSIX scheduling policy and parameters to parts of the thread configuration.

Parameters

	policy	is the POSIX scheduling policy.
	param	is the pointer to the POSIX scheduling parameters.
[out]	config	is the pointer to a thread configuration to set the budget algorithm, callout, and CPU time budget.

Return values

0	The operation was successful.
EINVAL	The POSIX scheduling policy or parameters were invalid.

Variable Documentation

_POSIX_Threads_Default_attributes

const pthread_attr_t _POSIX_Threads_Default_attributes

extern

This variable contains the default POSIX Thread attributes.

_POSIX_Threads_Information

Thread_Information _POSIX_Threads_Information

extern

The following defines the information control block used to manage this class of objects.

_POSIX_Threads_User_thread_table

const posix_initialization_threads_table _POSIX_Threads_User_thread_table

extern

Initialization table for the first user POSIX thread.

This table is used by _POSIX_Threads_Initialize_user_thread() and initialized via <rtems/confdefs.h>.
