escape_nul

Description:

[ Version ( since = "2.30" ) ]
public static string escape_nul (char[] str)

Escapes the nul characters in string to "\x00".

It can be used to compile a regex with embedded nul characters.

For completeness, length can be -1 for a nul-terminated string. In this case the output string will be of course equal to string.

length	the length of `string`
string	the string to escape

a newly-allocated escaped string
