Finding Timestamp of a File in C?

[kelon]

Hi,

I was just wondering how you would determine the date/timestamp of a file using C. Thanks.

Time stamps can be read by using the stat() function. For more information... try man stat.

#include <stdio.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <time.h>

main()
{
int status = 0;
struct stat statData;

status = stat(&quot;MyFile.dat&quot;, &statData);

if(status == -1)
{
/*
*
* Some error occured, should use errno to check
* but for this example... just exit.
*
*/
fprintf(stderr, &quot;stat() failed.&quot;
exit(1);
}

printf(&quot;Last Modification : %s&quot;,
ctime(&statData.st_mtime));
printf(&quot;Last Access : %s&quot;,
ctime(&statData.st_atime));
printf(&quot;Last Change Of File Status: %s&quot;,
ctime(&statData.st_ctime));

return 0;
}

This is platform dependent, so your compiler may not provide stat(). If you're on a Windows environment, try GetFileAttributesEx().
