* Name: futimens
|
|
*
|
|
* Description:
|
|
* futimens() update the timestamps of a file with nanosecond precision.
|
|
* This contrasts with the historical utime(2) and utimes(2), which permit
|
|
* only second and microsecond precision, respectively, when setting file
|
|
* timestamps.
|
|
*
|
|
* Input Parameters:
|
|
* fd - Specifies the fd to be modified
|
|
* times - Specifies the time value to set
|
|
*
|
|
* Returned Value:
|
|
* On success, futimens() return 0.
|
|
* On error, -1 is returned and errno is set to indicate the error.
