pthread_rwlockattr_init() function is used to
initialize a read/write lock attributes object.
The pthread_rwlockattr_destroy() function
is used to destroy a read/write lock attribute object previously created
with pthread_rwlockattr_init().
The pthread_rwlockattr_getpshared()
function shall obtain the value of process-shared attribute from the
initialized attributes object referenced by attr.
The pthread_rwlockattr_setpshared()
function shall set the process-shared attribute in an initialized attributes
object referenced by attr.
pthread_rwlockattr_init() shall fail if:
ENOMEM]pthread_rwlockattr_init() and
pthread_rwlockattr_destroy() may fail if:
EINVAL]pthread_rwlockattr_getpshared() and
pthread_rwlockattr_setpshared() may fail if:
EINVAL]pthread_rwlockattr_getpshared() and
pthread_rwlockattr_setpshared() functions are hidden
by default since only thread shared attributes are supported.
