cgigetvalue(3) - Linux man page
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.
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.
