PROLOG         top

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

NAME         top

       utime.h — access and modification times structure

SYNOPSIS         top

       #include <utime.h>

DESCRIPTION         top

       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         top

       The utime() function only allows setting file timestamps to the
       nearest second.  Applications should use the utimensat() function
       instead. See <sys/stat.h>.

RATIONALE         top

       None.

FUTURE DIRECTIONS         top

       The <utime.h> header may be removed in a future version.
