NAME
cgiGetValue - Return the value of a CGI variable
SYNOPSYS
#include <cgi.h>
I char *cgiGetValue (s_cgi * parms , const char * name );
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
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.
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.
