@CHIP-RTOS C Library - Common Gateway Interface API

CGI_UrlEncode

Encodes a URL string

void CGI_UrlEncode ( char *dst,
                      const char far *src );

Parameters

dst

Output Parameter: Pointer to the buffer the encoded string is to be stored in; must be large enough. The encoded string can be up to three times as large as the original string.

src

String that is to be encoded

Comments

In URL-encoded strings all non-alphanumerical characters except '-', '_' and '.' are encoded as a hexadecimal value preceded by a percent sign (e.g. %26 for the ampersand). The space character is replaced by a plus sign. The text "Test 123 .&%" (without the quotes) would be encoded as "Test+123+.%26%25".
This kind of encoding is for example used to pass arguments to a CGI page with the URL.
