NAME
catgets - Retrieves a message from a catalog
LIBRARY
Standard C Library (libc)
SYNOPSIS
#include <nl_types.h>
char *catgets(
nl_catd cat_descriptor,
int set_number,
int message_number,
const char *string);
STANDARDS
Interfaces documented on this reference page conform to industry standards as follows:
catgets(): XSH5.0
Refer to the standards(5) reference page for more information about industry standards and associated tags.
PARAMETERS
Specifies a catalog descriptor that is returned by the catopen() function. Identifies a message set. Identifies a message. In combina-
tion, the set_number and message_number identify the particular message in the catalog to retrieve. Specifies the default message string
to be returned if catgets() cannot retrieve the message from the catalog.
DESCRIPTION
The catgets() function retrieves a message from a catalog after a successful call to the catopen() function. If the catgets() function
finds the specified message, a pointer to the message text is returned. Otherwise, the function returns a pointer to the default message
string.
NOTES
The returned cat_descriptor pointer is not valid once the catclose() function has been called for that cat_descriptor.
RETURN VALUES
On successful completion, the catgets() function returns a pointer to the null terminated message string retrieved from the catalog. Oth-
erwise, the function returns a pointer to string and sets errno to indicate the error.
ERRORS
If the catgets() function fails, it sets errno to one of the following values for the reason specified: [Tru64 UNIX] Search permission is
denied for a component of the path to the message catalog or read permission is denied for the catalog.
[Tru64 UNIX] This error may occur on the first invocation of catgets(). See catopen(3) for more information. The cat_descriptor
value does not identify a message catalog that is open for reading. The cat_descriptor argument is corrupted. [Tru64 UNIX] The
process limit for open file descriptors per process has already reached OPEN_MAX.
[Tru64 UNIX] This error may occur on the first invocation of catgets(). See catopen(3) for more information. [Tru64 UNIX] The
system limit for open file descriptors has been reached. [Tru64 UNIX] The message catalog does not exist.
[Tru64 UNIX] This error may occur on the first invocation of catgets(). See catopen(3) for more information. [Tru64 UNIX] Insuf-
ficient memory is available.
[Tru64 UNIX] This error may occur on the first invocation of catgets(). See catopen(3) for more information. The message identi-
fied by set_number and message_number is not in the catalog.
