NAME
catgets -- retrieve string from message catalog LIBRARY
Standard C Library (libc, -lc) SYNOPSIS
#include <nl_types.h> char * catgets(nl_catd catd, int set_id, int msg_id, const char *s); DESCRIPTION
The catgets() function attempts to retrieve message msg_id of set set_id from the message catalog referenced by the descriptor catd. The argument s points to a default message which is returned if the function is unable to retrieve the specified message. RETURN VALUES
If the specified message was retrieved successfully, catgets() returns a pointer to an internal buffer containing the message string; other- wise it returns s. ERRORS
The catgets() function will fail if: [EBADF] The catd argument is not a valid message catalog descriptor open for reading. [EINTR] The operation was interrupted by a signal. [ENOMSG] The message identified by set_id and msg_id is not in the message catalog. SEE ALSO
gencat(1), catclose(3), catopen(3), nls(7) STANDARDS
The catgets() function conforms to X/Open Portability Guide Issue 4, Version 2 (``XPG4.2''). Major Unix vendors are split over the adoption of the two most important message catalog specifications: catgets or gettext(3). The primary concern with the catgets interface is that every translatable string has to define a number (or a symbolic constant) which must correspond to the message in the catalog. Duplicate message IDs are not allowed. Constructing message catalogs is difficult. BSD

NAME
catgets - read a program message SYNOPSIS
#include <nl_types.h> char *catgets(nl_catd catd, int set_num, int msg_num, const char *s); DESCRIPTION
The catgets() function attempts to read message msg_num, in set set_num, from the message catalog identified by catd. The catd argument is a catalog descriptor returned from an earlier call to catopen(). The s argument points to a default message string which will be returned by catgets() if the identified message catalog is not currently available. RETURN VALUES
If the identified message is retrieved successfully, catgets() returns a pointer to an internal buffer area containing the null termi- nated message string. If the call is unsuccessful for any reason, catgets() returns a pointer to s and errno may be set to indicate the error. ERRORS
The catgets() function may fail if: EBADF The catd argument is not a valid message catalogue descriptor open for reading. EBADMSG The number of %n specifiers that appear in the message string specified by s does not match the number of %n specifiers that appear in the message identified by set_id and msg_id in the specified message catalog. EINTR The read operation was terminated due to the receipt of a signal, and no data was transferred. EINVAL The message catalog identified by catd is corrupted. ENOMSG The message identified by set_id and msg_id is not in the message catalog. USAGE
The catgets() function can be used safely in multithreaded applications as long as setlocale(3C) is not being called to change the locale. ATTRIBUTES
