cgiGetValue3

Synopsys

#include <cgi.h>

char *cgiGetValue (s_cgi *parms, const char *name);

Overview

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.
