catgets — get message from a message catalog
#include <nl_types.h>
char
*catgets( |
nl_catd catalog, |
| int set_number, | |
| int message_number, | |
const char *message); |
catgets() reads the message
message_number, in
set set_number, from
the message catalog identified by catalog, where catalog is a catalog descriptor
returned from an earlier call to catopen(3). The fourth
argument message
points to a default message string which will be returned by
catgets() if the identified
message catalog is not currently available. The message-text
is contained in an internal buffer area and should be copied
by the application if it is to be saved or modified. The
return string is always terminated with a null byte.
On success, catgets()
returns a pointer to an internal buffer area containing the
null-terminated message string. On failure, catgets() returns the value message.
These functions are only available in libc.so.4.4.4c and
above. The Jan 1987 X/Open Portability Guide specifies a more
subtle error return: message is returned if the
message catalog specified by catalog is not available, while
an empty string is returned when the message catalog is
available but does not contain the specified message. These
two possible error returns seem to be discarded in SUSv2 in
favor of always returning message.
