End of Response Processing (Exit Point 8)

Allows you to override the internal data value created during the execution of the application.

Syntax:

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

On Entry:

exit point
8 = End of response processing
exit_info
version
Version of structure format
flags
0
funcs
User exit support functions
request_cxt
version Version of structure format
service_type Type of client request
display_buf_len Length of data in display_buf
flags Request context control flags
service_name Name of loaded service
pgm_name Name of the main program associated with the service
epoint_name Name of the entry point to invoke
display_buf Concatenation of strings output by ANSI DISPLAY statements
response
response_len Length of response_buf
flags Control flags
response_buf Response buffer created by default mapping or overridden by the exit
content_type NULL-terminated content type string (HTTP only)
exit_data
User exit-specific data

On Exit:

exit_info
response
response_len Length of response_buf
response_buf 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 processing
IDP_EXIT_STOP
1 = Terminate response processing. The default response is not to be sent. An error response will be required
IDP_EXIT_HANDLED
2 = The exit has overridden the default response

Comments:

This exit gives you the opportunity to override the full response generated by default mapping. The exit can optionally modify any of the returned request fields listed above. The exit should use the fn_alloc_mem support function of the exit_info funcs structure to allocate any memory used to replace the response_buf field. If the exit chooses to override any of the response structure fields, it must 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.
