What is the section '0P' in man page?
manpage
Solution
Under Linux, at least, the `p` stands for POSIX.
Section `0p` is the header files, `1p` is the commands and `3p` is the functions.
Problem
After reading the `stdbool.h` man page its section number, `0P`, drew my attention. Does it describe `*.h` files or something like that? I can't find the answer.
