NAME ^

POSIX::1003::Properties - POSIX access to _POSIX_ constants

INHERITANCE ^

 POSIX::1003::Properties
   is a POSIX::1003::Module

SYNOPSIS ^

  use POSIX::1003::Properties;     # import all

  use POSIX::1003::Properties 'property';
  $hasnt = property('_POSIX_NO_TRUNC');

  use POSIX::1003::Properties '_POSIX_NO_TRUNC';
  $hasnt = _POSIX_NO_TRUNC;

  use POSIX::1003::Properties '%property';
  my $key = $property{_POSIX_NO_TRUNC};
  $property{_POSIX_NEW} = $value;

  foreach my $prop (property_names) ...

DESCRIPTION ^

When you compile C/C++ programs, the header files provide you with a long list of _POSIX constants. This module pass these values on to Perl.

METHODS ^

POSIX::1003::Properties->exampleValue(NAME)

See "METHODS" in POSIX::1003::Module

$obj->import()

See "METHODS" in POSIX::1003::Module

FUNCTIONS ^

Standard POSIX

There is no system call to retrieve these values: they are defined in the C sources only.

Additional

property(NAME)

Returns the property value related to NAME.

property_names()

Returns a list with all known names, unsorted.

CONSTANTS ^

%property

This exported variable is a tie HASH which contains the values related to the system property names.

The following constants where detected on your system when the module got installed. The second column shows the value which where returned at that time.
