File modification time as an int

How can I return the file modification time as an int (UNIX epoch)?
C Syntax (Toggle Plain Text) 
  1. #include <time.h>
  2. #include <sys/stat.h>
  3.  
  4. int *FILEMOD(char *FILENAME)
  5. {
  6. 	struct stat ATTRIBUTES;
  7. 	time_t MTIME;
  8.  
  9. 	stat(FILENAME, &ATTRIBUTES);
  10. 	MTIME = ATTRIBUTES.st_mtime;
  11.  
  12. 	return MTIME;
  13. }
  14.  
  15. int main(void)
  16. {
  17. 	printf("%i",FILEMOD("file.txt"));
  18.  
  19. 	return 0;
  20. }
gcc errors:
filemod.c: In function ‘FILEMOD’:
mod.c:14: warning: return makes pointer from integer without a cast
mod.c: In function ‘main’:
mod.c:19: warning: incompatible implicit declaration of built-in function ‘printf’

Just cast the return, time_t is equivalent to int for 32 bit OS.

C Syntax (Toggle Plain Text) 
  1. 	return (int) MTIME;

To fix the printf warning include stdio.h
