native_dynamic_form_value()

char * native_dynamic_form_value	(	const char *	body,
		const char *	key )

Extracts a value from a URL-encoded form body.

Searches body for key=value pairs separated by & and returns the decoded value for the first match.

Parameters

body	URL-encoded form body.
key	Form field name to look up.

Returns
