cgiGetValue

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.
