KRB5_CONFIG(3)

NAME
krb5_config_get_bool_default, krb5_config_get_int_default, krb5_config_get_string_default, krb5_config_get_time_default - get configuration value

LIBRARY
Kerberos 5 Library (libkrb5, -lkrb5)

SYNOPSIS
#include <krb5/krb5.h>
krb5_boolean
krb5_config_get_bool_default(krb5_context context, krb5_config_section *c, krb5_boolean def_value, ...);
int
krb5_config_get_int_default(krb5_context context, krb5_config_section *c, int def_value, ...);
const char*
krb5_config_get_string_default(krb5_context context, krb5_config_section *c, const char *def_value, ...);
int
krb5_config_get_time_default(krb5_context context, krb5_config_section *c, int def_value, ...);

DESCRIPTION
These functions get values from the krb5.conf(5) configuration file, or another configuration database specified by the c parameter.

The variable arguments should be a list of strings naming each subsection to look for. For example:

    krb5_config_get_bool_default(context, NULL, FALSE, "libdefaults", "log_utc", NULL)

gets the boolean value for the log_utc option, defaulting to FALSE.

krb5_config_get_bool_default() will convert the option value to a boolean value, where ‘yes’, ‘true’, and any non-zero number means TRUE, and any other value FALSE.

krb5_config_get_int_default() will convert the value to an integer.

krb5_config_get_time_default() will convert the value to a period of time (not a time stamp) in seconds, so the string ‘2 weeks’ will be converted to 1209600 (2 * 7 * 24 * 60 * 60).

BUGS
Other than for the string case, there's no way to tell whether there was a value specified or not.
