tis_rwlock_init - Initializes a read-write lock object
tis_rwlock_t *lock );
Standard C Library (libc.so, libc.a)
Address of a read-write lock object.
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
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
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.
