NAMEutime.h — access and modification times structure
SYNOPSIS
#include <utime.h>
DESCRIPTION
The <utime.h> header shall declare the utimbuf structure, which shall
include the following members:
time_t actime Access time.
time_t modtime Modification time.
The times shall be measured in seconds since the Epoch.
The <utime.h> header shall define the time_t type as described in
<sys/types.h>.
The following shall be declared as a function and may also be defined
as a macro. A function prototype shall be provided.
int utime(const char *, const struct utimbuf *);
The following sections are informative.
APPLICATION USAGE
The utime() function only allows setting file timestamps to the nearest
second. Applications should use the utimensat() function instead. See
<sys/stat.h>.
RATIONALE
None.
FUTURE DIRECTIONS
The <utime.h> header may be removed in a future version.
