PTHREAD_GETSPECIFIC(3) BSD Library Functions Manual PTHREAD_GETSPECIFIC(3) NAME pthread_getspecific -- get a thread-specific data value LIBRARY Reentrant C Library (libc_r, -lc_r) POSIX Threads Library (libpthread, -lpthread) 1:1 Threading Library (libthr, -lthr) SYNOPSIS #include <pthread.h> void * pthread_getspecific(pthread_key_t key); DESCRIPTION The pthread_getspecific() function returns the value currently bound to the specified key on behalf of the calling thread. The effect of calling pthread_getspecific() with a key value not obtained from pthread_key_create() or after key has been deleted with pthread_key_delete() is undefined. The pthread_getspecific() function may be called from a thread-specific data destructor 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, then the value NULL is returned. ERRORS None. SEE ALSO pthread_key_create(3), pthread_key_delete(3), pthread_setspecific(3) STANDARDS The pthread_getspecific() function conforms to ISO/IEC 9945-1:1996 ("POSIX.1"). BSD April 4, 1996 BSD
