catgets - read a program message
Návod, kniha: POSIX Programmer's Manual
#include <nl_types.h>
char *catgets(nl_catd
catd, int
set_id , int
msg_id , const char
*s);
The
catgets() function shall attempt to read message
msg_id, in
set
set_id, from the message catalog identified by
catd. The
catd argument is a message catalog descriptor returned from an earlier
call to
catopen(). The
s argument points to a default message
string which shall be returned by
catgets() if it cannot retrieve the
identified message.
The
catgets() function need not be reentrant. A function that is not
required to be reentrant is not required to be thread-safe.
If the identified message is retrieved successfully,
catgets() shall
return a pointer to an internal buffer area containing the null-terminated
message string. If the call is unsuccessful for any reason,
s shall be
returned and
errno may be set to indicate the error.
The
catgets() function may fail if:
- EBADF
- The catd argument is not a valid message catalog
descriptor open for reading.
- EBADMSG
- The message identified by set_id and msg_id
in the specified message catalog did not satisfy implementation-defined
security criteria.
- 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.
