pthread_key_delete(3P)

NAME
     pthread_key_delete - thread-specific data key deletion

C SYNOPSIS
     #include <pthread.h>

     int pthread_key_delete(pthread_key_t key);

DESCRIPTION
     The pthread_key_delete() function deletes a key that was previously
     returned by pthread_key_create().

     When key is deleted, the associated destructor (if any) is not called by
     pthread_key_delete() nor will it be called upon thread exit [see
     pthread_exit()].  It is the responsibility of the user program to free up
     any storage that is referenced by key.

     The use of key after the call to pthread_key_delete() will result in
     undefined behavior.

DIAGNOSTICS
     On success, pthread_key_delete() returns zero; otherwise, an error number
     is returned:

     [EINVAL]       The value specified by key is invalid.
