NAME

       gfs_utimes - set file access and modification times

SYNOPSIS

       #include <gfarm/gfarm.h>

       char *gfs_utimes (const char * gfarm_url, const struct gfarm_timespec *
       tsp);

DESCRIPTION

       gfs_utimes() sets the access and modification times of the file pointed
       to by the gfarm_url argument to the value of the tsp argument.  The tsp
       argument is an array of gfarm_timespec  structures.   The  first  array
       member represents the access time, and the second member represents the
       modification time.  The gfarm_timespec structure is:

            struct gfarm_timespec {
                 unsigned int tv_sec;     /* seconds */
                 unsigned int tv_nsec;    /* nanoseconds */
            };

       If the tsp argument is a null  pointer,  the  access  and  modification
       times of the file are set to the current time.
