Hi,

In the above code just forget about the file d1.txt(do not consider it). And the code if working perfectly fine. Suppose after some time if i get 2nd datafile i want the good and bad records related to 2nd data file should be stored with a different name. It should not overwrite the existing validated files. So eachtime it should create a goodrec and badrec files with a timestamp attached to the filename.

Below are the configfile and datafile:
configfile.txt:
Code:
id,Integer(2),NOT NULL
name,String(20)
state,String(5),NOT NULL
phone_no,Integer(4)
gender,Char(1)

datafile.txt
Code:
1,John,MI,4589,M
2,Lilly,FL,589,F
3,Richard,CA,2212,M
4,Cruse,VA,2222,M
5a,Taylor,,5888,M

load_datafile(3alleg4)						  Allegro manual					    load_datafile(3alleg4)

NAME
load_datafile - Loads a datafile into memory. Allegro game programming library. SYNOPSIS
#include <allegro.h> DATAFILE *load_datafile(const char *filename); DESCRIPTION
Loads a datafile into memory in one go. If the datafile has been encrypted, you must first call packfile_password() to set the appropriate key. If the datafile contains truecolor graphics, you must set the video mode or call set_color_conversion() before loading it. Example: /* Load the resources for our game. */ DATAFILE *dat = load_datafile("game.dat"); if (!dat) abort_on_error("Couldn't load sound resources!"); /* Use resources. */ ... /* Destroy them when we don't need them any more. */ unload_datafile(dat); RETURN VALUE
Returns a pointer to the DATAFILE, or NULL on error. Remember to free this DATAFILE later to avoid memory leaks. SEE ALSO
