Detailed Description

Information for a server connection.

Member Data Documentation

TDSRESULTINFO* tds_socket::current_results

Current query information.

Contains information in process, both normal and compute results. This pointer shouldn't be freed; it's just an alias to another structure.

unsigned char* tds_socket::in_buf

Input buffer.

Points to receiving packet buffer. As input buffer contains just the raw packet actually this pointer is the address of recv_packet->buf.

volatile unsigned char tds_socket::in_cancel

indicate we are waiting a cancel reply; discard tokens till acknowledge; 1 mean we have to send cancel packet, 2 already sent.

TDSLOGIN* tds_socket::login

config for login stuff.

After login this field is NULL

unsigned char* tds_socket::out_buf

Output buffer.

Points to sending packet buffer. Output buffer can contain additional data before the raw TDS packet so this buffer can point some bytes after send_packet->buf.

unsigned int tds_socket::out_buf_max

Maximum size of packet pointed by out_buf.

The buffer is actually a bit larger to make possible to do some optimizations (at least TDS_ADDITIONAL_SPACE bytes).
