DECthreads POSIX 1003.1c Library (libpthread.so)
Address of the read-write lock 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 read-write lock object
specified by rwlock 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
If the specified read-write lock 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 rwlock is invalid.
