NAME

       getgrnam, getgrgid - get group file entry

SYNOPSIS

       #include <grp.h>
       #include <sys/types.h>

       struct group *getgrnam(const char *name);

       struct group *getgrgid(gid_t gid);

DESCRIPTION

       The  getgrnam()	function  returns a pointer to a structure containing the group information from /etc/group for the entry that matches the
       group name name.

       The getgrgid() function returns a pointer to a structure containing the group information from /etc/group for the entry	that  matches  the
       group gid gid.

       The group structure is defined in <grp.h> as follows:

	      struct group {
		      char    *gr_name;        /* group name */
		      char    *gr_passwd;      /* group password */
		      gid_t   gr_gid;	       /* group id */
		      char    **gr_mem;        /* group members */
	      };

RETURN VALUE

       The  getgrnam()	and  getgrgid()  functions  return the group information structure, or NULL if the matching entry is not found or an error
       occurs.

ERRORS

       ENOMEM Insufficient memory to allocate group information structure.
