Debug Assertaion Failure

[AndyHollywood]

Does anybody know why I would get a debug assertion failure when i run my program? It seems to happen when when i try to output to a text file with the following code;

FILE *pKBLog;
/*DLL ATTACH*/
pKBLog = fopen("d:\\logs\\_kblog.txt", "w" /* Open log */
fprintf(pKBLog, "Andrew/n"

/*DLL DETACH*/
fclose(pKBLog);

For some reason i get an assertion error, evem though from what i have read i am using the functions properly.

Hope some one can help me

Cheers in advance

maybe if you gave a hint what assertion and where... Hope that this helped! ;-)

oh yeah..sorry

Its in:
File: fprintf.c
Line: 56
Expression: str !=NULL

and while debugging the dll it happens when it trys to execute the follwoing line:
fprintf(pKBLog, "Andrew/n"

Hope that helps

It suggests that the fopen() failed and the file pointer is null. Hope that this helped! ;-)
