Can someone please tell me why calloc is not working.
The following is a piece of the code. The letter 'A' is
printing but not the letter 'B'.
printf("\nA");
//Prepare variables.
tmpstr4 = (char*)calloc(TMAXSTRINGLENGTH, sizeof(char));
if(tmpstr4 == NULL){
printf("Error main0000002 - Failed to allocate memory in GetEnvironmentPaths.\n");
return TMEMALLOCFAILED;
}
printf("\nB");

Presumably your error message is output?
If so, presumably TMAXSTRINGLENGTH is a very large number?
The error message is not displayed. The program crashes during
the call to the function. I recently changed the runtime library to
LIBCMT.lib instead of MSVCRT.LIB during linking of the program
but neither libraries are working.
Can you show a minimal (console) application that anyone can build to reproduce the problem please.
I got it to work. The problem was that TMAXSTRINGLENGTH was not
large enough to contain the string. What I did was times it by 4 to
allocate enough memory.
Thank you for your help and concern on the matter.
I am glad you have got your solution and thanks for your sharing, I would appreciate it if you mark them as answer and this will be beneficial to other community.
