PTHREAD_GETSPECIFIC(3) BSD Library Functions Manual PTHREAD_GETSPECIFIC(3) NAME pthread_getspecific -- get a thread-specific data value SYNOPSIS #include <pthread.h> void * pthread_getspecific(pthread_key_t key); DESCRIPTION The pthread_getspecific() function returns the value that is currently bound to the specified key, on behalf of the calling thread. The effect of calling pthread_getspecific() with a key value that was not obtained from pthread_key_create(), or after a key has been deleted with pthread_key_delete(), is undefined. pthread_getspecific() may be called from a thread-specific data destruc-tor destructor tor function. RETURN VALUES The pthread_getspecific() function will return the thread-specific data value associated with the given key. If no thread-specific data value is associated with key, the value NULL is returned. ERRORS None. SEE ALSO pthread_key_create(3), pthread_key_delete(3), pthread_setspecific(3) STANDARDS pthread_getspecific() conforms to ISO/IEC 9945-1:1996 (``POSIX.1''). BSD April 4, 1996 BSD |
