NAME
cgiGetCookie - Return a cookie
SYNOPSYS
#include <cgi.h>
s_cookie *cgiGetCookie (s_cgi *parms, const char *name);
DESCRIPTION
This routine returns a pointer to a s_cookie structure that contains
all values for the cookie as referenced by name. The pointer must not
be freed.
The s_cookie structure is declared as follows:
typedef struct cookie_s {
char *version,
*name,
*value,
*path,
*domain;
} s_cookie;
Memory allocated by this data structure is automatically freed by the
final call to cgiFree(3).
To set a cookie in your program you’ll need to manually add additional
header lines. Please take a look at cgitest.c. Basically, you’ll need
to add the following code:
cgiSetHeader ("Set-Cookie", "Version=1; name=value; Path=/");
cgiHeader();
Please read the included file cookies.txt as well.
RETURN VALUE
On success a pointer to a s_cookie structure is returned. If no cookie
was set or no cookie with a given name exists NULL is returned.
