NAME
getconf - get system configuration values
SYNOPSIS
specification] system_var
specification] system_var pathname
DESCRIPTION
The command provides an interface to the and library routines and system calls.
The system_var argument specifies the configuration value desired in or Use the first synopsis form for inquiries involving or Refer to in
this manpage. Use the second synopsis form for inquiries involving Refer to in this manpage. For inquiries involving the pathname operand
should be specified.
For a complete list of parameters supported by see sysconf(2), pathconf(2), and confstr(3C).
Options
recognizes the following option:
Return configuration variables corresponding to
a particular compilation environment supported by HP-UX. If the option is not specified, specification defaults
to XBS5_ILP32_OFF32. See table below for possible specifications and meanings.

EXTERNAL INFLUENCES
Environment Variables
determines the language in which messages are displayed.
If is not specified in the environment or is set to the empty string, the value of is used as a default for each unspecified or empty vari-
able. If is not specified or is set to the empty string, a default of "C" (see lang(5)) is used instead of
If any internationalization variable contains an invalid setting, behaves as if all internationalization variables are set to "C". See
environ(5).

One or more missing operands.
Operand was not recognized.
pathname
either invalid or inaccessible.
EXAMPLES
Request the number of intervals per second:

Inquire if the implementation supports multiple locality domains:
gives the following output:
If the implementation supports multiple locality domains.
If the implementation does not support multiple locality domains.
Inquire if the system supports Numeric User Group Name feature (see usergroupname(5)):
gives the following output:
If the system supports Numeric User Group Name.
If the system does not support Numeric User Group Name.
