NAME
       cgiGetValue - Return the value of a CGI variable

SYNOPSYS
       #include <cgi.h>

       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.

       Memory allocated by the returned value is automatically	freed  by  the
       final call to cgiFree(3).

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.

AUTHOR
       This CGI library is written by Martin Schulze <joey@infodrom.org>.   If
       you have additions or improvements please get in touch with him.
