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.
