dns_api_msg Struct Reference

#include <api_msg.h>

Data Fields

const char * name
 
ip_addr_taddr
 
u8_t dns_addrtype
 
sys_sem_t * sem
 
err_terr
 

Detailed Description

As lwip_netconn_do_gethostbyname requires more arguments but doesn't require a netconn, it has its own struct (to avoid struct api_msg getting bigger than necessary). lwip_netconn_do_gethostbyname must be called using tcpip_callback instead of tcpip_apimsg (see netconn_gethostbyname).
