Detailed Description

General utility functions.

Function Documentation

wget_path_sanitize()

char * wget_path_sanitize

(

const char *

path

)

Parameters

[in]

path

Input path to sanitize

Returns

Newly allocated sanitized path, or NULL on error

Sanitizes the given file path by resolving ".", "..", and multiple slashes.

Examples: "/root/foo/../bar/.//x.txt" -> "/root/bar/x.txt" "foo/../bar" -> "bar" "/foo/./bar" -> "/foo/bar" "/foo//bar" -> "/foo/bar" "foo/bar/.." -> "foo" ".." -> ".." (preserved, cannot resolve past root) "/../foo" -> "/foo" (stays at root) "" -> "." (empty path becomes current directory)

The returned string must be freed with wget_free().
