How to get list of function signatures from header files

Question

Working through PSET1 - Credit. I'm coming to CS50 with experience in languages other than C, with strong documentation, and it would be really helpful to be able to generate a list of function signatures (and descriptions, if available) that are available in the header files at the top of my C files.

Here's the code I have so far:

#include <stdio.h>
#include <cs50.h>

int main(void) {
    printf("Number: "); 
    long long num = get_long_long(); 
    while(num < 0) {
        printf("Retry: "); 
        num = get_long_long(); 
}

I would assume there's a way to get a list of functions for these headers from the terminal, similar to running man man for the standard library functions. Is this possible? If so, what's the best way?

Answer 1

It is difficult to respond in a simple way, without going into great depths we can find very good documentation in man pages: We can find documentation of the standard head files by typing in the terminal

info stdio

or

man stdio

for example. With non-standard files like cs50.h this does not work, but we can find all the header files in the path

/user/include/

and open them in read mode.

I hope that helps
