Including and Excluding API Functions

By defining functions to be included in, or excluded from, the file system, you can control the amount of space it uses. This is more manageable than using libraries, where adding or removing a piece of code can cause unpredictable changes in the size of your code.

Every entry in the above table which has the text "Enables <function name>" in the Description column is a function that you can disable if you do not need it in your system. For example, setting the F_CHDIR option to 0 disables the f_chdir() function.

The F_FINDING option disables two functions: f_findfirst() and f_findnext().
