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 Hesiod 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
representation 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.
