pthread_key_setname_np - Change the object name in a thread-specific data key object.
DECthreads POSIX 1003.1c Library (libpthread.so)
const char *name,
Address of the thread-specific data key object whose object name is to be changed. Object name value to copy into the thread-specific data key object. Reserved for future use. The value must be zero (0).
This routine changes the object name in the thread-specific data key object specified by key to the value specified by name. To set a new thread-specific data key object's object name, call this routine immediately after initializing the key object.
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 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, or the length in characters of name exceeds 31. Insufficient memory exists to create a copy of the object name string.
