Macro Definition Documentation

HTTP_IS_DATA_VOLATILE

#define HTTP_IS_DATA_VOLATILE

(

hs

)

Value:

(((hs->file != NULL) && (hs->handle != NULL) && (hs->file == \
                                   (const char*)hs->handle->data + hs->handle->len - hs->left)) \
                                   ? 0 : TCP_WRITE_FLAG_COPY)

These defines check whether tcp_write has to copy data or not This was TI's check whether to let TCP copy data or not #define HTTP_IS_DATA_VOLATILE(hs) ((hs->file < (char *)0x20000000) ? 0 : TCP_WRITE_FLAG_COPY)Default: don't copy if the data is sent from file-system directly

HTTP_IS_HDR_VOLATILE

#define HTTP_IS_HDR_VOLATILE	(		hs,
			ptr
	)		0

Default: headers are sent from ROM

MIN_REQ_LEN

#define MIN_REQ_LEN   7

Minimum length for a valid HTTP/0.9 request: "GET /\r\n" -> 7 bytes
