Send a message to the system logger
#include <stdio.h> #include <sys/slog.h> int slogb( int code, int severity, void * data, int size );
libc
Use the -l c option to qcc to link against this library. This library is usually included automatically.
The slog*() functions send log messages to the system logger, slogger. To send formatted messages, use slogf(). If you have programs that scan log files for specified codes, you can use slogb() or slogi() to send a block of structures or ints, respectively.
(QNX Neutrino 6.6) You can't redirect slogger output to slogger2 in general, but if a program uses the slogger APIs, you can preload the libslog2shim.so library when you start the program, in order to redirect its logs:
LD_PRELOAD=libslog2shim.so my_program
Any value from the Errors section in MsgSend(), as well as:
See slogf().
