Detailed Description

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_CPU_budget_algorithms *	budget_algorithm,
		Thread_CPU_budget_algorithm_callout *	budget_callout
	)

Translate sched_param into SuperCore terms.

This method translates the POSIX API sched_param into the corresponding SuperCore settings.

Parameters

[in]	policy	is the POSIX scheduling policy
[in]	param	points to the scheduling parameter structure
[in]	budget_algorithm	points to the output CPU Budget algorithm
[in]	budget_callout	points to the output CPU Callout

Return values

0	Indicates success.
error_code	POSIX error code indicating failure.

_POSIX_Threads_Sporadic_budget_callout()

void _POSIX_Threads_Sporadic_budget_callout

(

Thread_Control *

the_thread

)

POSIX threads sporadic budget callout.

This routine handles the sporadic scheduling algorithm.

Parameters

[in]

the_thread

is a pointer to the thread whose budget has been exceeded.

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>.
