Function Documentation

issize_t http_extract_body	(	msg_t *	msg,
		http_t *	http,
		char	b[],
		isize_t	bsiz,
		int	eos
	)

Extract HTTP message body.

Return values:

	-1	error
	0	cannot proceed
	other	number of bytes extracted

http_method_t http_method_d	(	char **	ss,
		char const **	nname
	)

Parse a HTTP method name.

The function http_method_d() parses a HTTP method, and returns a code corresponding to the method. It stores the address of the first non-LWS character after method name in *ss.

Parameters:

	ss	pointer to pointer to string to be parsed
	nname	pointer to value-result parameter formethod name

Note:: If there is no whitespace after method name, the value in *nname may not be NUL-terminated. The calling function must NUL terminate the value by setting the **ss to NUL after first examining its value.

Returns:: The function http_method_d returns the method code if method was identified, 0 (http_method_unknown) if method is not known, or -1 (http_method_invalid) if an error occurred.

If the value-result argument nname is not NULL, http_method_d() stores a pointer to the method name to it.

issize_t http_query_parse	(	char *	query,
			...
	)

Parse query part in HTTP URL.

The function http_query_parse() searches for the given keys in HTTP query. For each key, a query element (in the form name=value) is searched from the query string. If a query element has a beginning matching with the key, a copy of the rest of the element is returned in corresponding return_value argument.

Note:: The query string will be modified.

Returns:: The function http_query_parse() returns number keys that matched within the query string.

int http_version_d	(	char **	ss,
		char const **	ver
	)

Parse HTTP version.

The function http_version_d() parses a HTTP method.

Return values:

	0	when successful,
	-1	upon an error.
