Start of Response Processing (Exit Point 5)

Allows you to bypass completely the default response processing.

Syntax:

typedef cblt_rtncode (*PFI_IDP_EXIT)(mf_uns32      exit_point,
                                     IDP_EXIT_INFO *exit_info);

On Entry:

exit point

5 = Start of response processing

exit_info

version

Version of structure format

flags

funcs

User exit support functions

request_cxt

version	Version of structure format
argc	Parameter count of loaded service
return_code	Service's return code, or run-time error generated by service
service_type	Type of client request
display_buf_len	Length of data in display_buf
flags	Request context control flags
protocol_attrs	An array of pointers to protocol-specifc attributes
argv	Parameter list of loaded service
service_name	Name of loaded service
pgm_name	Name of the main program associated with the service
display_buf	Concatenation of strings output by ANSI DISPLAY statements

response

flagss	Control flags
response_type	Server's response type

exit_data

User exit-specific data

On Exit:

exit_info

flags

response

response_len	Length of response_buf
flags	Control flags
response_buf	Server's response buffer
content_type	NULL-terminated content type string (HTTP) only

exit_data

User exit-specific data

Return codes:

IDP_EXIT_CONTINUE: 0 = Continue with default response processing
IDP_EXIT_STOP: 1 = Terminate mapping processing. An error response will be required
IDP_EXIT_HANDLED: 2 = The entire response has been built by the exit. No further processing is required. The response is ready to be sent back to the client.

Comments:

This exit gives you the opportunity to bypass completely the default response processing. If the exit wants the default response processing to be bypassed, it must set up the response fields indicated above as being returned fields, using the fn_alloc_mem support function of the exit_info funcs structure to allocate the memory for the response buffer, and return IDP_EXIT_HANDLED.

The user exit program owns the exit_data field of the IDP_EXIT_INFO structure. You would typically use it to preserve context information between exit point invocations. You can use it when returning any of the IDP_EXIT_ return values.
