Macro Definition Documentation

POSIX_TIMER_RELATIVE

#define POSIX_TIMER_RELATIVE   0

Indicates that the fire time is relative to the current one

POSIX_TIMER_STATE_CREATE_NEW

#define POSIX_TIMER_STATE_CREATE_NEW   0x02

Created timer but not running

POSIX_TIMER_STATE_CREATE_RUN

#define POSIX_TIMER_STATE_CREATE_RUN   0x03

Created timer and running

POSIX_TIMER_STATE_CREATE_STOP

#define POSIX_TIMER_STATE_CREATE_STOP   0x04

Created, ran and stopped timer

POSIX_TIMER_STATE_FREE

#define POSIX_TIMER_STATE_FREE   0x01

Timer is free

Function Documentation

_POSIX_Timer_Allocate()

RTEMS_INLINE_ROUTINE POSIX_Timer_Control* _POSIX_Timer_Allocate

(

void

)

POSIX Timer Allocate.

This function allocates a timer control block from the inactive chain of free timer control blocks.

_POSIX_Timer_Free()

RTEMS_INLINE_ROUTINE void _POSIX_Timer_Free

(

POSIX_Timer_Control *

the_timer

)

POSIX Timer Free.

This routine frees a timer control block to the inactive chain of free timer control blocks.

_POSIX_Timer_Get()

RTEMS_INLINE_ROUTINE POSIX_Timer_Control* _POSIX_Timer_Get	(	timer_t	id,
		ISR_lock_Context *	lock_context
	)

POSIX Timer Get.

This function maps timer IDs to timer control blocks. If ID corresponds to a local timer, then it returns the timer control pointer which maps to ID and location is set to OBJECTS_LOCAL. Otherwise, location is set to OBJECTS_ERROR and the returned value is undefined.
