TCPIP_HTTP_ArgGet Function

const uint8_t* TCPIP_HTTP_ArgGet(
    const uint8_t* cData, 
    const uint8_t* cArg
);

This function searches through a data array to find the value associated with a given argument. It can be used to find form field values in data received over GET or POST.

The end of data is assumed to be reached when a null name parameter is encountered. This requires the string to have an even numner of null-terminated strings, followed by an additional null terminator.

The data array has a vlaid series of null terminated name/value pairs.

A pointer to the argument value or NULL if not found.

None.
