29?S: This variable defines Gid_t to be something like gid_t, int,

34?C: This symbol holds the return type of getgid() and the type of

36?C: it is the type of group ids in the kernel. It can be int, ushort,
37?C: uid_t, etc... It may be necessary to include <sys/types.h> to get
38?C: any typedef'ed information.
