Hi,

I try to create the hooks for open()/fopen().

hook code:
#include <stdio.h>

int open(const char *fname, int mode, ...) {
	printf("fname=%s\n", fname);
}

FILE* fopen(const char *fname, const char *mode) {
	printf("fname=%s\n", fname);
}


test code:
#include <stdio.h>

int main() {
	FILE *file = fopen("main.c", "rb");
	if ( file ) fclose(file);
}


compiled as:
gcc hook.c -shared -oopenhook.dll
gcc main.c -omain

run as:
LD_PRELOAD=/home/niXman/openhook.dll ./main

But a can't see the output.
What I am doing wrongly?

Thanks!
