Hello List,
I wanted to generate tmp files by mktemp() and mkstemp() in a C++
program. The use of these 2 functions result in segmentation faults.
How do i use these ?
Heres how i'm using them
______________________
mkstemp("tempXXXXXX");
______________________
GCC--> 2.96
OS--> RedHat 7.1
Kernel--> 2.5.6
TIA
Tc

#include <stdlib.h>
#include <string.h>
#include <stdio.h>
int main(){
char tmp[32];
strncpy(tmp, "tmpXXXXXX", 32);
mkstemp(tmp);
printf("%s\n", tmp);
return 0;
}
You're using a constant string, and you're not allowed to write to constant
strings.
