Use the -l c option to qcc to link against this library. This library is usually included automatically.
This function is in libc.a, but not in libc.so (in order to save space). |
The slog*() functions send log messages to the system logger, slogger. To send formatted messages, use vslogf(). If you have programs that scan log files for specified codes, you can use slogb() or slogi() to send a block of structures or int's, respectively.
This function is a “varargs” version of slogf().
