/ ************************************************************************ * * Purpose: Program to demonstrate the 'stat' function. * The program will show the modification and access times * plus the size of a file. * * Author: M J Leslie * * Date: 01-Jun-95 MJL Minor bug fixed. * 13-Apr-95 MJL Inital Release * * Notes: This function is only available to Unix systems. If you * are on a DOS machine, this will not compile. * * Compile: Change the #define (below) to a suitable file name on your * system. The file name is not passed on the command line * as I did not want to complicate the example. * ************************************************************************/ #include <sys/stat.h> /* declare the 'stat' structure */ #include <sys/types.h> #include <unistd.h> #include <stdio.h> /* printf */ #include <time.h> #define FILENAME "martin" /* PUT YOUR FILE NAME HERE */ /************************************************************************/ char * format_time(time_t cal_time); void file_stat(char * filename); /************************************************************************/ main() { file_stat(FILENAME); } /************************************************************************/ void file_stat(char * filename) { struct stat stat_p; /* 'stat_p' is a pointer to a structure * of type 'stat'. */ /* Get stats for file and place them in * the structure. */ if ( -1 == stat (filename, &stat_p)) { printf(" Error occoured attempting to stat %s\n", filename); exit(0); } /* Print a few structure members. */ printf("Stats for %s \n", filename); printf("Modify time is %s", format_time(stat_p.st_mtime)); /* Access time does not get updated if the filesystem is NFS mounted! */ printf("Access time is %s", format_time(stat_p.st_atime)); printf("File size is %d bytes\n", stat_p.st_size); } /************************************************************************/ char * format_time(time_t cal_time) { struct tm *time_struct; static char string[30]; /* Put the calendar time into a structure * if type 'tm'. */ time_struct=localtime(&cal_time); /* Build a formatted date from the * structure. */ strftime(string, sizeof string, "%h %e %H:%M\n", time_struct); /* Return the date/time */ return(string); }
