[Configuration options for uIP]

Detailed Description

An uIP application is implemented using a single application function that is called by uIP whenever a TCP/IP event occurs. The name of this function must be registered with uIP at compile time using the UIP_APPCALL definition.

uIP applications can store the application state within the uip_conn structure by specifying the size of the application structure with the UIP_APPSTATE_SIZE macro.

The file containing the definitions must be included in the uipopt.h file.

The following example illustrates how this can look.

void httpd_appcall(void);
#define UIP_APPCALL     httpd_appcall

struct httpd_state {
  u8_t state; 
  u16_t count;
  char *dataptr;
  char *script;
};
#define UIP_APPSTATE_SIZE (sizeof(struct httpd_state))

Defines
#define	UIP_APPCALL   smtp_appcall
	The name of the application function that uIP should call in response to TCP/IP events.
#define	UIP_APPSTATE_SIZE   (sizeof(struct smtp_state))
	The size of the application state that is to be stored in the uip_conn structure.
