#define RFIFOB (  fd, pos   )

Value: (*(unsigned char*) \ (session[fd]->rdata + session[fd]->rdata_pos + (pos)))

#define RFIFOFLUSH (  fd   )

Value: do { \ memmove(session[fd]->rdata, \ RFIFOP(fd,0), RFIFOREST(fd)); \ session[fd]->rdata_size = RFIFOREST(fd); \ session[fd]->rdata_pos = 0; \ } while (0)

#define RFIFOL (  fd, pos   )

Value: (*(unsigned int*) \ (session[fd]->rdata + session[fd]->rdata_pos + (pos)))

#define RFIFOW (  fd, pos   )

Value: (*(unsigned short*) \ (session[fd]->rdata + session[fd]->rdata_pos + (pos)))

#define WPACKETB (  pos   )     (*(unsigned char*)(WPACKETBUF + (pos)))

Gets an unsigned char from the packet buffer. Could be used to read or write value. B in the name is for 'byte'. WPACKETB(0) = 20; // will write 20 into the buffer. Parameters: pos  Buffer index.

#define WPACKETL (  pos   )     (*(unsigned int*)(WPACKETBUF + (pos)))

Gets an unsigned int from packet buffer. L in the name is for 'long'. See also: WPACKETB()

#define WPACKETP (  pos   )     (WPACKETBUF + (pos))

Gets a pointer from the packet buffer. This operation is similar to &buffer[pos]. P in the name is for 'pointer'. Parameters: pos  Buffer index. Returns: Pointer to location.

#define WPACKETW (  pos   )     (*(unsigned short*)(WPACKETBUF + (pos)))

Gets an unsigned short from packet buffer. W in the name is for 'word'. See also: WPACKETB()

char WPACKETBUF[65536]

The Packet buffer. biggest paket: Guild storage with only equipement: 4 + 22 * 1000 = 22004, biggest have size in WPACKETW(2)
