Callback function prototype of the CGI response function.
- Parameters
-
| buffer | Output buffer where CGI response content will be copied to. |
| buffer_size | Size of the output buffer.
It's defined by the FNET_CFG_HTTP_REQUEST_SIZE_MAX parameter. |
| eof | Condition flag:
FNET_FALSE = there is still more data to send. The fnet_http_cgi_send_t function will be called during the next iteration again.FNET_FALSE = no more data is available for the CGI response. It was the last call of the fnet_http_cgi_send_t function for the current CGI response.
|
| cookie | This parameter points to the value, initially set to zero, which can be used to associate a custom information with a connection instance. If application store context information in the cookie, it will be preserved for future calls for this request. This allows the application to associate some request-specific state. |
- Returns
- This function returns the number of bytes actually written to the buffer pointed to by
buffer.
The condition flag eof indicates if the CGI data-end condition has occurred.
- See also
- fnet_http_cgi, fnet_http_cgi_handle_t
This function creates the CGI response content.
An application should use the buffer as output buffer for the dynamic content and set eof flag to 1 if no data for output are available.
The CGI handler invokes this callback function after successful call of the fnet_http_cgi_handle_t function and continues to call this function repeatedly till the eof will be set to 1 or the return result is set to 0.
