tis_rwlock_init(3)					     Library Functions Manual						tis_rwlock_init(3)

NAME

       tis_rwlock_init - Initializes a read-write lock object.

LIBRARY

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

SYNOPSIS

       #include <tis.h>

       int   tis_rwlock_init(
			      tis_rwlock_t   *lock);

STANDARDS

       None

PARAMETERS

       Address of a read-write lock object.

DESCRIPTION

       This routine initializes a read-write lock object.  The routine initializes 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
