In Linux, how do I get the man pages for C functions rather than shell commands?
For example, when I type man bind I get the manual page for the shell command bind and not the man page for socket binding C function.

To use man , you type man on the command line, followed by a space and a Linux command. man opens the Linux manual to the “man page” that describes that command—if it can find it, of course. The man page for man opens.
To search a specific man page section, use the -s option with the man command and the -k or -K option.
Each man page comes in sections. The table below shows the section numbers of the manual followed by the types of pages they contain: Section # 1 : User command (executable programs or shell commands) Section # 2 : System calls (functions provided by the kernel)
man command in Linux is used to display the user manual of any command that we can run on the terminal. It provides a detailed view of the command which includes NAME, SYNOPSIS, DESCRIPTION, OPTIONS, EXIT STATUS, RETURN VALUES, ERRORS, FILES, VERSIONS, EXAMPLES, AUTHORS and SEE ALSO.
man 2 bind You need a result from a different section of the manual! Man searches various sections for the information you want. As devnull lists below, the number indicates which section to search.
Incidentally, bind is a system call, not a C library function. System calls (kernel calls) are in section 2 of the manual, library functions are in section 3.
man man will tell you how to use the man command!
