unescape_segment

Description:

[ Version ( since = "2.16" ) ]
public static string? unescape_segment (string? escaped_string, string? escaped_string_end, string? illegal_characters = null)

Unescapes a segment of an escaped string.

If any of the characters in illegal_characters or the NUL character appears as an escaped character in escaped_string, then that is an error and null will be returned. This is useful if you want to avoid for instance having a slash being expanded in an escaped path element, which might confuse pathname handling.

Note: `NUL` byte is not accepted in the output, in contrast to unescape_bytes.

Parameters:

escaped_string	A string, may be null
escaped_string_end	Pointer to end of `escaped_string`, may be null
illegal_characters	An optional string of illegal characters not to be allowed, may be null

Returns:

an unescaped version of escaped_string, or null on error. The returned string should be freed when no longer needed. As a special case if null is given for escaped_string, this function will return null.
