getgrgid() -- General Function (libc)

#include <grp.h>
struct group *getgrgid(gid);
int gid;

getgrgid() searches  file /etc/group for  the first entry  with a numerical

Notes

All structures  and information returned  are in a static  area internal to
getgrgid(). Therefore,  information from a previous  call is overwritten by
each subsequent call.
