catgets - get message from a message catalog
Návod, kniha: Library Functions Manual
#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 XPG4.2 in favour of always returning
message.
