.TH MAGI 3 2020-05-02 v0.0.1 "Library Manual"
.SH NAME
.B magi
\- Common Gateway Interface (CGI) library
.SH SYNOPSIS
.B #include <magi.h>
.SH DESCRIPTION
The
.B magi
library gives the user a way to interact with the web server
through CGI as described in
.IR "RFC 3875" .
The library is free and open source software.
.SS Usage
A program using
.B magi
library must be linked with the
.B -lmagi
option.
.P
Main task of the
.B magi
library is to analyse CGI request and represent it to the user in
.B magi_request
data structure. This is done by calling
.B magi_parse
on initialized via
.B magi_request_init
request variable. After initialization the user is able to configure
limits on the input and setup callback to process files loaded as
.IR multipart/form-data .
The
.B magi
library comes with
.B magi_loadfiles
callback usable for the majority of cases.
.P
CGI response utilities are also provided. The CGI headers are
outputted with
.B magi_response
and its methods. You can output defaults (Content-Type: text/html;
Status: 200 Ok) by calling
.BR magi_response_default .
Utility to form urlencoded strings is provided via
.BR magi_urlenc .
.SS Error handling
If function is returning pointer, error is only in case of null returned.
If function is returning
.I int
as success mark it will be null only in case of error, and one otherwise.
Exact
.B magi_error
code is in
.B error
field of
.B magi_request
structure. For other modules error codes seem to be overkill.
