cgiGetValue - Return the value of a CGI variable
Contents
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).
