#include "stdio.h"

    int n = 0;
    int size = 0;
    char *comment;
    char module[1024];
    char blacklist[200][1024];
    FILE *stream;
    if((stream = fopen ("/etc/hotplug/blacklist", "r")) != (FILE *)0) {
       while((fgets(module, 1023, stream)) != (char *)0 ) {
	
		comment = strchr(module, '#');
		if (comment != 0) *comment = '\0';
		comment = strchr(module, '\n');
   		if (comment != 0) *comment = '\0';
		size = strlen(module);
		if (size < 2) continue;
		strcat (module , " \0");
		strcpy(blacklist[n] , module);
		n++;
	fprintf(stderr, module);
	}
    }
	else {
	fprintf(stderr, "file does not exist");
	}
return 0;
}
now that ad-hoc implementation got transformed into this patch.. yet to be tested. Ok I fixed the segfault.. AFAIK this should be usable. Thanks Uniball for helping, but I didn't use your code. I think this is simpler.
