NAME

gfs_utimes - set file access and modification times

SYNOPSIS

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.
