HESIOD(3) Library Functions Manual HESIOD(3)NAME
hesiod_getpwnam, hesiod_getpwuid, hesiod_free_passwd - Hesiod functions for retrieving passwd information
SYNOPSIS
#include <hesiod.h>
struct passwd *hesiod_getpwnam(void *context, const char *name)
struct passwd *hesiod_getpwuid(void *context, uid_t uid)
void hesiod_free_passwd(void *context, struct passwd *pw)
cc file.c -lhesiod
DESCRIPTION
This family of functions allows you to retrieve passwd database information using Hesiod. To perform lookups, you need an initialized Hes-
iod context; see hesiod(3) for details. You may look up passwd information by name or by uid; information is returned in the same format
as by getpwnam or getpwuid. It is the caller's responsibility to call hesiod_free_passwd with the returned passwd entry to free the
resources used by the passwd entry.
Hesiod queries for passwd information are made using the ``passwd'' or ``uid'' Hesiod type, using either the username or the decimal repre-
sentation of the uid as the Hesiod name. The corresponding records should be a colon-separated list of fields giving the username,
encrypted password, uid, gid, GECOS information, home directory, and shell of the user.
RETURN VALUES
On failure, hesiod_getpwnam and hesiod_getpwuid return NULL and set the global variable errno to indicate the error.
ERRORS
These calls may fail for any of the reasons the routine hesiod_resolve may fail.
