pthread_key_delete Subroutine

Purpose

Deletes a thread-specific data key.

Library

Threads Library (libpthreads.a)

Syntax

#include <pthread.h>

int pthread_key_delete (pthread_key_t key);

Description

The pthread_key_delete subroutine deletes the thread-specific data key key,
previously created with the pthread_key_create subroutine. The application must
ensure that no thread-specific data is associated with the key. No destructor
routine is called.

    Note: The pthread.h header file must be the first included file of each
    source file using the threads library. Otherwise, the -D_THREAD_SAFE
    compilation flag should be used, or the cc_r compiler used. In this case, the
    flag is automatically set.

Parameters

key Specifies the key to delete.

Return Values

If successful, the pthread_key_delete function returns zero. Otherwise, an error
number is returned to indicate the error.

Error Codes

The pthread_key_delete function will fail if:

EINVAL The key value is invalid.

The pthread_key_delete function will not return an error code of EINTR.

Implementation Specifics

This subroutine is part of the Base Operating System (BOS) Runtime.
