Detailed Description

Helper functions for parsing URI query parameters.

Function Documentation

int parse_query_parameter_value_from_query	(	const char *	query,
		const char *	parameter_name,
		const char **	parameter_value
	)

Parse a query parameter from a query and return the size of the parameter value and a pointer to the value within the query.

Example usage:

char *value_ptr = NULL;
ssize_t value_len = parse_query_parameter_value("someparameter=value&param2=second", "param2", &value_ptr);

will result in value_len = 6 and value_ptr = "second"

Parameters

	query	The query to parse.
	parameter_name	The parameter name to parse from the query.
[out]	parameter_value	A pointer to the parameter value, NULL if parameter does not exist.

Returns

The size of the parameter value, -1 if parameter does not exist in the query.

int parse_query_parameter_value_from_uri	(	const char *	uri,
		const char *	parameter_name,
		const char **	parameter_value
	)

Parse a query parameter from URI and return the size of the parameter value and a pointer to the value within the URI.

Example usage:

char *value_ptr = NULL;
ssize_t value_len = parse_query_parameter_value_from_uri("http://www.myquery.com?someparameter=value", "someparameter", &value_ptr);

will result in value_len = 5 and value_ptr = "value"

Parameters

	uri	The URI to parse.
	parameter_name	The parameter name to parse from query.
[out]	parameter_value	A pointer to the parameter value, NULL if parameter does not exist.

Returns

The size of the parameter value, -1 if parameter does not exist in the URI.
