# NAME

`pw_getconf`, `pw_getpwconf` —
password encryption configuration access function

# LIBRARY

System Utilities Library (libutil, -lutil)

# SYNOPSIS

`#include <util.h>`

void
`pw_getconf`(char *data, size_t len, const char *key, const char *option);

void
`pw_getpwconf`(char *data, size_t len, const struct passwd *pwd, const char *option);

# DESCRIPTION

The `pw_getconf`() function reads /etc/passwd.conf and retrieves the value of the option specified by option from the section given by key. If no suitable entry is found for the key an empty string will be returned in data.

To retrieve default values the key default can be used. In this case, if /etc/passwd.conf does not exist or does not contain a default section, the built-in defaults will be returned. They are as follows:

option | data
ypcipher | old
localcipher | old

An empty string is returned for all errors.

`pw_getpwconf`() returns the value for the option specified for the particular user specified in pwd. If that option is not found, then it tries to find the option in the primary group of that user, and if that fails, then it returns the default entry.

# FILES

/etc/passwd.conf

`pw_getconf`() and `pw_getpwconf`() will fail if:
