NAME
tis_key_delete - Deletes the specified thread-specific data key.
LIBRARY
Standard C Library (libc.so, libc.a)
SYNOPSIS
#include <tis.h>
int tis_key_delete(
pthread_key_t key);
STANDARDS
None
PARAMETERS
Thread-specific data key to be deleted.
DESCRIPTION
This routine deletes a thread-specific data key key previously returned by a call to the tis_key_create(3) routine. The data values asso-
ciated with key need not be NULL at the time this routine is called. The application must free any application storage or perform any
cleanup actions for data structures related to the the deleted key or associated data. This cleanup can be done before or after this rou-
tine is called.
Attempting to use the thread-specific data key key after calling this routine results in unpredictable behavior.
No destructor functions are invoked by this routine. Any destructor functions that may have been associated with key will no longer be
called upon thread exit.
This routine can be called from within destructor functions.
RETURN VALUES
If an error condition occurs, this routine returns an integer value indicating the type of error. Possible return values are as follows:
Successful completion. The value for key is invalid.
ERRORS
None
