NAME
catopen, catclose - open/close a message catalog
SYNOPSIS
#include <nl_types.h>
nl_catd catopen(const char *name, int flag);
int catclose(nl_catd catalog);
DESCRIPTION
The function catopen() opens a message catalog and returns a catalog
descriptor. The descriptor remains valid until catclose() or ex‐
ecve(2). If a file descriptor is used to implement catalog descrip‐
tors, then the FD_CLOEXEC flag will be set.
The argument name specifies the name of the message catalog to be
opened. If name specifies an absolute path (i.e., contains a '/'),
then name specifies a pathname for the message catalog. Otherwise, the
environment variable NLSPATH is used with name substituted for %N (see
locale(7)). It is unspecified whether NLSPATH will be used when the
process has root privileges. If NLSPATH does not exist in the environ‐
ment, or if a message catalog cannot be opened in any of the paths
specified by it, then an implementation defined path is used. This
latter default path may depend on the LC_MESSAGES locale setting when
the flag argument is NL_CAT_LOCALE and on the LANG environment variable
when the flag argument is 0. Changing the LC_MESSAGES part of the lo‐
cale may invalidate open catalog descriptors.
The flag argument to catopen() is used to indicate the source for the
language to use. If it is set to NL_CAT_LOCALE, then it will use the
current locale setting for LC_MESSAGES. Otherwise, it will use the
LANG environment variable.
The function catclose() closes the message catalog identified by cata‐
log. It invalidates any subsequent references to the message catalog
defined by catalog.
RETURN VALUE
The function catopen() returns a message catalog descriptor of type
nl_catd on success. On failure, it returns (nl_catd) -1 and sets errno
to indicate the error. The possible error values include all possible
values for the open(2) call.
The function catclose() returns 0 on success, or -1 on failure.
ENVIRONMENT
LC_MESSAGES
May be the source of the LC_MESSAGES locale setting, and thus
determine the language to use if flag is set to NL_CAT_LOCALE.
LANG The language to use if flag is 0.

NOTES
The above is the POSIX.1 description. The glibc value for NL_CAT_LO‐
CALE is 1. The default path varies, but usually looks at a number of
places below /usr/share/locale.
