System Functions (n - p) pthread_key_delete(2)
NAME
pthread_key_delete - Deletes a thread-specific data key
LIBRARY
G-series native OSS processes: /G/system/sysnn/zsptsrl
32-bit H-series and J-series OSS processes that use the POSIX User Thread Model library:
/G/system/zdllnnn/zputdll
64-bit H-series and J-series OSS processes that use the POSIX User Thread Model library:
/G/system/zdllnnn/yputdll
H-series and J-series OSS processes that use the Standard POSIX Threads library:
/G/system/zdllnnn/zsptdll
SYNOPSIS
#include <pthread.h> | #include <spthread.h>
/* pthread.h is required to use POSIX User Thread Model library */
/* spthread.h is required to use Standard POSIX Threads library */
int pthread_key_delete(
pthread_key_t key);
PARAMETERS
key Specifies the thread-specific data key to be deleted.
DESCRIPTION
This function deletes the thread-specific data key specified by the key parameter, which must
have been previously returned by the pthread_key_create() function.
The thread-specific data values associated with the specified key need not be NULL at the time
this function is called. The application must free any application storage or perform any cleanup
actions for data structures related to the deleted key or associated thread-specific data in any
threads. This cleanup can be done either before or after this function is called.
No destructor routines are invoked by this function. Any destructor routines that might have
been associated with the specified key are not called upon thread exit. pthread_key_delete()
can be called from within destructor routines.
On systems running H06.21 or later H-series RVUs or J06.10 or later J-series RVUs, you can use
either the POSIX User Thread Model library or the Standard POSIX Threads library for threaded
applications.
To use this function in a threaded application that uses the POSIX User Thread Model library on
systems running H06.21 or later RVUs or J06.10 or later RVUs, you must perform all of the fol-
lowing tasks:
• Include the pthread.h header file in the application.
• Compile the application using the _PUT_MODEL_ feature test macro or equivalent
compiler command option.
• Link the application to the zputdll library (/G/system/zdllnnn/zputdll).
On systems running H06.24 or later H-series RVUs or J06.13 or later J-series RVUs, you can use
the POSIX User Thread Model library with 32-bit or 64-bit threaded applications.
To use this function in a 32-bit threaded application that uses the POSIX User Thread Model
library on systems running H06.24 or later RVUs or J06.13 or later RVUs, perform the same
tasks (described above) used to enable the POSIX User Thread Model library on systems running
H06.21/J06.10 or later RVUs.
