GETGRAENT(3)  —  C LIBRARY FUNCTIONS

NAME

getgraent, getgranam, setgraent, endgraent, fgetgraent − get group adjunct file entry

SYNOPSIS

#include <grpadj.h>

struct group_adjunct ∗getgraent()

struct group_adjunct ∗getgranam(name)
char ∗name;

struct group_adjunct ∗fgetgraent(f)
FILE ∗f;

void setgraent()

void endgraent()

DESCRIPTION

getgraent() and getgranam() each return pointers to an object with the following structure containing the broken-out fields of a line in the group adjunct file.  Each line contains a group_adjunct structure, defined in the <grpadj.h> header file. 

struct  group_adjunct {
char    ∗gra_name;/∗ the name of the group ∗/
char    ∗gra_passwd;/∗ the encrypted group password ∗/
};

When first called, getgraent() returns a pointer to a group_adjunct structure corresponding to the first line in the file.  Thereafter, it returns a pointer to the next group_adjunct structure in the file.  So successive calls may be used to traverse the entire file. 

For locating a particular group, getgranam() searches through the file until it finds group filename, then returns a pointer to that structure.

A call to getgraent() rewinds the group adjunct file to allow repeated searches.  A call to endgraent() closes the group adjunct file when processing is complete. 

Because read access is required on /etc/security/group.adjunct, getgraent() and getgranam() will fail unless the calling process has effective UID of root. 

FILES

/etc/security/group.adjunct

DIAGNOSTICS

A NULL pointer is returned on end-of-file or error.
