C Programming in Linux – Is There Any Manual?

cdocumentationman

While I find that we can read some manuals about Library calls (C library functions) & acsii in Linux. But I still do not find any manual about C precedence order so far.

So you can recommend other useful manual about C now. Thank you!

PS: Note that the manual can be accessed via man command in Linux, so do not take those online manual or books into answers please.

man libc covers standard C libraries (glibc, Linux libc) on Linux.

In "SEE ALSO" section, there are

syscalls(2), feature_test_macros(7), man-pages(7), standards(7)

You can look into the details by

man 2 syscalls

man 7 feature_test_macros

man 7 man-pages

man 7 standards

From man man:

-K, --global-apropos
      Search for text in all manual  pages.   This  is  a  brute-force
      search,  and is likely to take some time; if you can, you should
      specify a section to reduce the number of pages that need to  be
      searched.   Search terms may be simple strings (the default), or
      regular expressions if the --regex option is used.

This directly opens the manpage (vim, then ex, then gview, ...) for me, so you could add another option, like -w to get an idea of which manpage will be displayed.

$ man -wK viminfo
/usr/share/man/man1/vim.1.gz
/usr/share/man/man1/vim.1.gz
/usr/share/man/man1/gvim.1.gz
/usr/share/man/man1/gvim.1.gz
/usr/share/man/man1/run-one.1.gz
/usr/share/man/man1/gvim.1.gz
/usr/share/man/man1/gvim.1.gz
/usr/share/man/man1/run-one.1.gz
/usr/share/man/man1/run-one.1.gz

Implicit declaration of strlcpy and strlcat even with “string.h” included

On Ubuntu, Mint, and relatives, strlcpy and strlcat are available in the libbsd-dev package. Run

sudo apt-get install libbsd-dev

This will install the libraries, header files, and man pages.

To use the functions from C code, add the line

#include <bsd/string.h>

to your files, and add -lbsd , or the more portable $(pkg-config --libs libbsd) , to your gcc command line to link the library.
