Yes, never lie to yourself, especially!

Type warnings:

You should match your subroutines to prototypes, usually by using the #include lines in man 2 xxx, or for main, explicitly say it returns int. For instance, with #include <strings.h>, strchr() is know to return char* not the default int, which is a type violation.

For your own subroutines, prototype them up top, if linked in your own #include "my_include_make_dir_or_minus_I_dir_relative_path_to_file". If they are in this file, you can use my favorite PASCAL cheat: declare/define them above main() or above wherever they are called, so you do not have to sync the prototype to any argument mods.

Remember boolean is int, so for instance, when you check to ensure your malloc succeeded:

Code:

if ( !(cptr=malloc(...)))

should be:

Code:

if ( !(int)(cptr=malloc(...)))

or:

Code:

if ((char*)NULL != (cptr=malloc(...)))

(I like putting the smaller and more constant operand on the left for easy reading.)



For instance, my "man 2 exit" says exit() needs: #include <stdlib.h>
