.SH NAME
cgiInit \- Initializes cgi library
.SH SYNOPSYS
.nf
.B #include <cgi.h>
.sp

.SH DESCRIPTION
This routine returns a pointer to the value of a cgi variable.
Encoded characters (%nn) are already decoded. One must not free the
pointer.
If
.B multiple
fields are used (i.e. a variable that may contain several values) the
value returned contains all these values concatenated together with a
newline character as separator.
.SH "RETURN VALUE"
On success a pointer to a string is returned. If the variable wasn't
transmitted through CGI or was empty NULL is returned.
.SH "AUTHOR"
This cgi library is written by Martin Schulze
<joey@infodrom.north.de>. If you have additions or improvements
please get in touch with him.
