* Name: settimeofday
|
2009-07-12 01:39:33 +02:00
|
|
|
*
|
|
|
|
* Description:
|
2015-02-12 18:10:46 +01:00
|
|
|
* Set the current time
|
|
|
|
*
|
|
|
|
* Conforming to SVr4, 4.3BSD. POSIX.1-2001 describes gettimeofday() but
|
|
|
|
* not settimeofday().
|
|
|
|
*
|
|
|
|
* NuttX implements settimeofday() as a thin layer around clock_settime();
|
|
|
|
*
|
|
|
|
* Input Parameters:
|
|
|
|
* tv - The net to time to be set
|
|
|
|
* tz - Ignored
|
|
|
|
*
|
2018-02-01 17:00:02 +01:00
|
|
|
* Returned Value:
|
2015-02-12 18:10:46 +01:00
|
|
|
* Zero (OK) on success; -1 is returned on failure with the errno variable
|
|
|
|
* set appropriately.
