int yes=1;
//char yes='1'; // Solaris people use this

When the ANSI C standard was under development, the pragma directive was introduced. Borrowed from Ada, #pragma is used to convey hints to the compiler, such as the desire to expand a particular function in-line or suppress range checks. Not previously seen in C, pragma met with some initial resistance from a gcc implementor, who took the "implementation-defined" effect very literally—in gcc version 1.34, the use of pragma causes the compiler to stop compiling and launch a computer game instead!

lmao

int setsockopt(int socket, int level, int option_name, const void *option_value, socklen_t option_len);

What kind of abomination is this function signature
