lwIP Options Configuration
Main packet buffer struct.
s8_t err_t
Define LWIP_ERR_T in cc.h if you want to use a different type for your platform (must be signed)...
IP address structure for passing IP addresses by value.
TCP API (to be used from TCPIP thread) See also tcp_raw.
IP address API (common IPv4 and IPv6)
Base TCP API definitions shared by TCP and ALTCP See also tcp_raw.
