NAME
       tis_rwlock_init - Initializes a read-write lock object

SYNOPSIS
       #include <tis.h>

       int tis_rwlock_init(
	       tis_rwlock_t *lock );

LIBRARY
       Standard C Library (libc.so, libc.a)

STANDARDS
       None

PARAMETERS
       Address of a read-write lock object.

DESCRIPTION
       This routine initializes a read-write lock object. The routine initialā€
       izes the tis_rwlock_t structure that holds the object's lock states.

       To destroy a read-write lock  object,  call  the	 tis_rwlock_destroy(3)
       routine.

       NOTE:  The  tis	read-write lock has no relationship to the Single UNIX
       Specification, Version 2 (SUSV2, or UNIX98)  read-write	lock  routines
       (pthread_rwlock_init(3),	 etc).	The  tis_rwlock_t type, in particular,
       cannot be used with the pthread read-write lock functions;  nor	can  a
       pthread_rwlock_t type be used with the tis read-write lock functions.

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 lock is not a valid
       read-write lock.	 Insufficient memory exists to initialize lock.

ERRORS
       None
