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.
