Function Documentation

makedir()

int makedir

(

char *

newdir

)

Creates a directory and all necessary parent directories.

This function attempts to create the directory specified by newdir. It handles the creation of parent directories recursively. It aborts if an ENOENT error is encountered, but ignores other errors such as when the directory already exists.

Parameters

newdir

The path of the directory to create.

Returns

int Returns 1 if the directory was created successfully, 0 on error.
