Function Documentation

multipart_parse()

bool multipart_parse	(	HttpReq *	req,
		Multipart *	mp
	)

Parse the body of req as multipart/form-data.

Reads the boundary from the Content-Type header, then scans req->body in-place, null-terminating each part's headers and data.

Parameters

req	Fully-parsed HTTP request (must be in PARSE_COMPLETE state).
mp	Output structure; filled on success.

Returns

true if at least one part was found, false on parse error.

multipart_get_field()

const char * multipart_get_field	(	const Multipart *	mp,
		const char *	field
	)

Look up a field value across all parsed parts by name.

Returns the data pointer of the first part whose name matches field. Useful for simple form submissions where each field has a unique name.

Parameters

mp	Parsed multipart result.
field	Form field name to search for.

Returns

Part data (null-terminated), or nullptr if not found.
