Name

pthread_rwlock_timedwrlock - lock a read-write lock for writing +

Synopsis

#include <pthread.h>
#include <time.h> +

int pthread_rwlock_timedwrlock(pthread_rwlock_t *restrict +rwlock, const struct timespec *restrict abs_timeout); + +

Description

The pthread_rwlock_timedwrlock function shall apply a write +lock to the read-write lock referenced by rwlock as in the +pthread_rwlock_wrlock(3) +function. However, if the lock cannot be acquired without waiting for +other threads to unlock the lock, this wait shall be terminated when +the specified timeout expires. The timeout shall expire when the +absolute time specified by abs_timeout passes, as measured by +the clock on which timeouts are based (that is, when the value of +that clock equals or exceeds abs_timeout), or if the absolute +time specified by abs_timeout has already been passed at the +time of the call. +

The timespec data type is defined in the <time.h> +header. Under no circumstances shall the function fail with a timeout +if the lock can be acquired immediately. The validity of the +abs_timeout parameter need not be checked if the lock can be +immediately acquired. +

The calling thread may deadlock if at the time the call is made it +holds the read-write lock. The results are undefined if this function +is called with an uninitialized read-write lock. +

Pthreads-w32 defines _POSIX_READER_WRITER_LOCKS in +pthread.h as 200112L to indicate that the reader/writer routines are +implemented and may be used.

Return Value

The pthread_rwlock_timedwrlock function shall return zero +if the lock for writing on the read-write lock object referenced by +rwlock is acquired. Otherwise, an error number shall be +returned to indicate the error. +

Errors

The pthread_rwlock_timedwrlock function shall fail if: +

ETIMEDOUT +: + The lock could not be acquired before the specified timeout expired. +

+The pthread_rwlock_timedwrlock function may fail if: +

EINVAL +: + The value specified by rwlock does not refer to an initialized + read-write lock object, or the abs_timeout nanosecond value + is less than zero or greater than or equal to 1000 million. +

+This function shall not return an error code of [EINTR]. +

The following sections are informative. +

Examples

None. +

Application Usage

Applications using this function may be subject to priority +inversion, as discussed in the Base Definitions volume of +IEEE Std 1003.1-2001, Section 3.285, Priority Inversion. +

Rationale

None. +

Future Directions

None. +
