Gets date and time.
Format
#include <time.h>
int gettimeofday (struct timeval *tp, void *tpz);
Arguments
- tp
- Pointer to a timeval structure, defined in the <time.h> header
file.
- tpz
- A NULL pointer. If this argument is not a NULL pointer, the
behavior is unspecified.
Description
This function gets the current time (expressed as seconds and
microseconds) since 00::00 Coordinated Universal Time, January 1,
1970. The current time is stored in the timeval structure pointed to
by the tp argument.
The tzp argument is intended to hold time-zone information
set by the kernel. However, because the OpenVMS kernel does not set
time-zone information, the tzp argument should be NULL.
If it is not NULL, it is ignored. This function is supported for
compatibility with BSD programs.
Return Values
| 0 | Indicates success. |
| -1 | An error occurred. errno is set
to indicate the error. |
