Usage -Magi main purpose is to analyse request and provide it in 'struct magi_request' -variable. It is described in 'src/request.h'; to setup defaults before actual -processing run 'magi_request_setup'. Next step is to analyse post-unrelated -part of request via 'magi_request_cgi'. Since post part can be realy big, -it is generally useful to constrain its analysis biased on the rest of request. -Post part analyse is done via 'magi_request_resume_cgi'. You can destroy -request structure via 'magi_request_destroy'. +magi_request analyses incoming request, general workflow is to: +1. Prepare request for analysis, setup defaults via 'magi_request_setup'; +2. Process non-post part of the CGI request via 'magi_request_cgi'; + (The division of post and non-post analysis comes from the fact that + post body can be really huge, so you probably will want to specify + some constraints on it, based on non-post info.

Content type need to be specified for response, to set it run -'magi_response_content_type'. You can set cookie with 'magi_response_cookie', -as well as discard them with 'magi_response_cookie_discard'. You can set HTTP -headers with 'magi_response_http'. For filling response body use -'magi_response_add' and 'magi_response_add_format'. To send response call -'magi_response_cgi'. Desctruction is provided in 'magi_response_destroy'. +magi_response provides output capabilities. You can form the response with +'magi_response_setup' used to setup defaults, and the following functions to +fill in your data ('...' means 'magi_response_'): + ...content_type: set Content Type (by default XHTML); + ...cookie: set HTTP Cookie; +...cookie_discard: discard HTTP Cookie; + ...http: setup arbitarary HTTP header; + ...add: add something to the body; + ...add_format: add comething to the body, using format (similar to printf); +Outputting itself can be done with 'magi_response_cgi'. +To correctly free all occupied memory call 'magi_response_destroy'. +For more see 'src/response.h'.
