cgiGetValue - Return the value of a CGI variable
#include <cgi.h>
char *cgiGetValue (s_cgi *parms, const char *name);
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.
On success a pointer to a string is returned. If the variable wasn’t transmitted through CGI or was empty NULL is returned.
This CGI library is written by Martin Schulze <joey@infodrom.north.de>. If you have additions or improvements please get in touch with him.
