Convert from unsigned char array to long c

Question

I read the longest from the binary into an unsigned char buffer using fread.

Now I would like to get a long one. How to do it?

unsigned char buffer[sizeof(long)]; fread(buffer, sizeof(long), 1, my_file); 

thanks!

Answer 1

Surely you mean:

 long buffer; fread(&buffer, sizeof(long), 1, my_file);
