The OMCGI library contains one macro and two OmniMark functions to simplify writing CGI programs with OmniMark. The functions allow you to retrieve and decode CGI input data and CGI-related environment variables.
CRLF macro allows you to easily use
%13#%10#, instead of
%n, to insert
new lines in your CGI programs. Using the
CRLF macro instead of
%n ensures the portability of
your code across platforms. You need to declare
binary-mode so that
all systems will properly interpret the
%13#%10# new line sequence.
You must also declare
#process-input stream as
unbuffered. If you do not, on some
systems your CGI program will hang.
#process-input is bound to standard input and used by your CGI program
to receive POST data. This leaves
#main-input free to receive a file name as an OmniMark command-line name
To use OMCGI, you must include the following code at the beginning of your program:
