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
