Detailed Description

These functions are used to issue queries on a connection. Single queries are made using the drizzle_query function, or you can queue multiple queries and run them concurrently using the other query functions.

Enumeration Type Documentation

DRIZZLE_API drizzle_result_st* drizzle_query	(	drizzle_con_st *	con,
		drizzle_result_st *	result,
		const char *	query,
		size_t	size,
		drizzle_return_t *	ret_ptr
	)

Send query to server. A drizzle_result_st will be created for the results.

Parameters:

[in]	con	connection to use to send the query.
[in,out]	result	pointer to an unused structure that will be used for the results, or NULL to allocate a new structure.
[in]	query	query string to send.
[in]	size	length of the query string in bytes.
[out]	ret_ptr	pointer to the result code.

Returns:: result, a pointer to the newly allocated result structure, or NULL if the allocation failed.
