Detailed Description

POSIX Thread Cancelation Support.

This file contains the prototypes and data types used to implement POSIX thread cancelation.

Function Documentation

_POSIX_Thread_Evaluate_cancellation_and_enable_dispatch()

void _POSIX_Thread_Evaluate_cancellation_and_enable_dispatch

(

Thread_Control *

the_thread

)

POSIX evaluate thread cancelation and enable dispatch.

This routine separates a piece of code that existed as part of another routine, but had to be separated to improve coverage.

Parameters

[in]

the_thread

is a pointer to the thread to evaluate canceling

_POSIX_Threads_cancel_run()

void _POSIX_Threads_cancel_run

(

Thread_Control *

the_thread

)

POSIX run thread cancelation.

This support routine runs through the chain of cancel handlers that have been registered and executes them.

Parameters

[in]

the_thread

is a pointer to the thread whose cancelation handlers should be run
