fwrite write an integer
- by user149100
I'm trying to write a word to a file using this function:
extern void write_int(FILE * out, int num) {
fwrite(&num,sizeof(int),1, out);
if(ferror(out)){
perror(__func__);
exit(EXIT_FAILURE);
}
}
But I get a segmentation fault whenever it tries to run the fwrite. I looked at the man page for fwrite(3) and I feel like I used it correctly, is there something I'm missing?
