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:

]pthread_rwlockattr_getpshared
() and

() may fail if:

]pthread_rwlockattr_getpshared
() and
pthread_rwlockattr_setpshared
() functions are hidden
by default since only thread shared attributes are supported.
