catclose(3) Library Functions Manual catclose(3) NAME
catclose - Closes a specified message catalog LIBRARY
Standard C Library (libc.so, libc.a) SYNOPSIS
#include <nl_types.h> int catclose( nl_catd cat_descriptor); STANDARDS
Interfaces documented on this reference page conform to industry standards as follows: catclose(): XPG4 Refer to the standards(5) reference page for more information about industry standards and associated tags. PARAMETERS
Specifies a message catalog descriptor that was returned from a call to the catopen() function. DESCRIPTION
The catclose() function closes the message catalog identified by cat_descriptor. Before exiting, programs should close any message catalogs they have opened. If a program accesses several message catalogs, the NL_MAXOPEN number of open catalogs can be reached. In this event, some message cata- logs must be closed before more can be opened. NOTES
The cat_descriptor pointer is not valid once the catclose() function has been called for that cat_descriptor. RETURN VALUES
On successful completion, the catclose() function returns a value of 0 (zero). Otherwise, the function returns a value of -1. (The func- tion will return -1 if interrupted by a signal or if the catalog descriptor is invalid.) ERRORS
The catalog descriptor is not valid. RELATED INFORMATION

CATOPEN(3) Linux Programmer's Manual CATOPEN(3) 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 execve(2). If a file descriptor is used to implement catalog descriptors, 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 envi- ronment, 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 vari- able when the flag argument is 0. Changing the LC_MESSAGES part of the locale 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 catalog. 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. ATTRIBUTES

POSIX.1-2001, POSIX.1-2008. NOTES
The above is the POSIX.1 description. The glibc value for NL_CAT_LOCALE is 1. The default path varies, but usually looks at a number of places below /usr/share/locale. SEE ALSO
