pthread_rwlock_setname_np(3)				     Library Functions Manual				      pthread_rwlock_setname_np(3)

NAME

       pthread_rwlock_setname_np - Changes the object name in a read-write lock object.

LIBRARY

       DECthreads POSIX 1003.1c Library (libpthread.so)

SYNOPSIS

       #include <pthread.h>

       int   pthread_rwlock_setname_np(
			     pthread_rwlock_t	       *rwlock,
			     const char 	       *name,
			     void		       *mbz);

PARAMETERS

       Read-write lock object whose object name is to be changed.  Object name value to copy into the read-write lock object.  Reserved for future
       use. The value must be zero (0).

DESCRIPTION

       This routine changes the object name in the read-write lock object specified by rwlock to the value specified by name. To set a	new  read-
       write lock object's object name, call this routine immediately after initializing the read-write lock 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.

RETURN VALUES

       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, or the length in characters of name exceeds 31.  Insufficient memory
       exists to create a copy of the object name string.

ERRORS

       None

pthread_rwlock_getname_np(3)				     Library Functions Manual				      pthread_rwlock_getname_np(3)

NAME

       pthread_rwlock_getname_np - Obtain the object name from a read-write lock object.

LIBRARY

       DECthreads POSIX 1003.1c Library (libpthread.so)

SYNOPSIS

       #include <pthread.h>

       int   pthread_rwlock_getname_np(
			     pthread_rwlock_t	       *rwlock,
			     char		       *name,
			     size_t		       len);

PARAMETERS

       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.

DESCRIPTION

       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 31.

       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.

RETURN VALUES

       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.

ERRORS

       None
