pthread_key_getname_np - Obtain the object name from a thread-specific data key object.
DECthreads POSIX 1003.1c Library (libpthread.so)
Address of the thread-specific data key object whose object name is to be obtained. Location to store the obtained object name. Length in bytes of buffer at the location specified by name.
This routine copies the object name from the thread-specific data key object specified by key to the buffer at the location name. Before calling this routine, your program must allocate the buffer indicated by name.
The object name is a C language string and provides an identifier that is meaningful to a person debugging a DECthreads-based multithreaded application. The maximum number of characters in the object name is 31.
If the specified thread-specific data key object has not been previously set with an object name, this routine copies a C language null string into the buffer at location name.
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 specified by key is invalid.
