pthread_key_delete(3)

NAME

     pthread_key_delete -- delete a thread-specific data key


LIBRARY

     Reentrant C Library (libc_r, -lc_r)
     POSIX Threads Library (libpthread, -lpthread)
     1:1 Threading Library (libthr, -lthr)


SYNOPSIS

     #include <pthread.h>

     int
     pthread_key_delete(pthread_key_t key);


DESCRIPTION

     The pthread_key_delete() function deletes a thread-specific data key pre-
     viously returned by pthread_key_create().	The thread-specific data val-
     ues associated with key need not be NULL at the time that
     pthread_key_delete() is called.  It is the responsibility of the applica-
     tion to 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
     pthread_key_delete() is called.  Any attempt to use key following the
     call to pthread_key_delete() results in undefined behavior.

     The pthread_key_delete() function is callable from within destructor
     functions.  Destructor functions are not invoked by pthread_key_delete().
     Any destructor function that may have been associated with key will no
     longer be called upon thread exit.


RETURN VALUES

     If successful, the pthread_key_delete() function will return zero.  Oth-
     erwise an error number will be returned to indicate the error.


ERRORS

     The pthread_key_delete() function will fail if:

     [EINVAL]		The key value is invalid.


SEE ALSO

     pthread_getspecific(3), pthread_key_create(3), pthread_setspecific(3)


STANDARDS

     The pthread_key_delete() function conforms to ISO/IEC 9945-1:1996
     (``POSIX.1'').
