3.1 Finding modules

There are three ways of finding the names of Gnulib modules that you can use in your package:

• You have the complete module list, sorted according to categories, in http://www.gnu.org/software/gnulib/MODULES.html.
• If you are looking for a particular POSIX header or function replacement, look in the chapters Header File Substitutes and Function Substitutes. For headers and functions that are provided by Glibc but not standardized by POSIX, look in the chapters Glibc Header File Substitutes and Glibc Function Substitutes.
• If you have already found the source file in Gnulib and are looking for the module that contains this source file, you can use the command ‘gnulib-tool --find filename’.
