utime.h(3)                 POSIX Programmer's Manual                utime.h(3)



PROLOG
       This manual page is part of the POSIX Programmer's Manual.  The OS
       implementation of this interface may differ (consult the corresponding
       OS manual page for details of OS behavior), or the interface may not be
       implemented on OS.

NAME
       utime.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.
