Field Declarations for Clients

Functions
drizzle_field_t	drizzle_field_read (drizzle_result_st *result, size_t *offset, size_t *size, size_t *total, drizzle_return_t *ret_ptr)
drizzle_field_t	drizzle_field_buffer (drizzle_result_st *result, size_t *total, drizzle_return_t *ret_ptr)
void	drizzle_field_free (drizzle_field_t field)

Detailed Description

These functions allow you to access fields in a result set if the result is unbuffered. If the result is buffered, you can access the fields through the row functions.

Function Documentation

drizzle_field_read()

drizzle_field_t drizzle_field_read	(	drizzle_result_st *	result,
		size_t *	offset,
		size_t *	size,
		size_t *	total,
		drizzle_return_t *	ret_ptr )

Read field for unbuffered result, possibly in parts. This is especially useful for blob streaming, since the client does not need to buffer the entire blob.

drizzle_field_buffer()

drizzle_field_t drizzle_field_buffer	(	drizzle_result_st *	result,
		size_t *	total,
		drizzle_return_t *	ret_ptr )

Buffer one field.

drizzle_field_free()

void drizzle_field_free

(

drizzle_field_t

field

)

Free a buffered field.
