C
BYTE* HTTPURLDecode( BYTE* cData );
Description
Parses a string from URL encoding to plain-text. The following conversions are made: ‘=’ to ‘0’, ‘&’ to ‘0’, ‘+’ to ‘ ‘, and “%xx” to a single hex byte.
After completion, the data has been decoded and a null terminator signifies the end of a name or value. A second null terminator (or a null name parameter) indicates the end of all the data.
Preconditions
The data parameter is null terminated and has at least one extra byte free.

cData |
The string which is to be decoded in place. |
Returns
A pointer to the last null terminator in data, which is also the first free byte for new data.
