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

NAME

       pthread_rwlockattr_init - Initialize a read-write lock attributes object.

LIBRARY

       DECthreads POSIX 1003.1c Library (libpthread.so)

SYNOPSIS

       #include <pthread.h>

       int   pthread_rwlockattr_init(
			     pthread_rwlockattr_t	  *attr);

PARAMETERS

       Address of the read-write lock attributes object to be initialized.

DESCRIPTION

       This routine initializes the read-write lock attributes object referenced by attr and sets its attributes with default values.

       The results of calling this routine are undefined if attr references an already initialized read-write lock attributes object.

       After  an  initialized  read-write lock attributes object has been used to initialize one or more read-write lock objects, any operation on
       that attributes object (including destruction) has no effect on those read-write lock objects.

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.  Insufficient memory exists to initialize the read-write lock attributes object.

ERRORS

       None
