vslog2fa()

Log a printf-style string in a slog2 buffer (varargs)

Synopsis:

#include <sys/slog2.h>

int vslog2fa( slog2_buffer_t buffer,
              uint16_t code,
              uint8_t severity,
              const char* format,
              va_list arglist );

Arguments:

buffer
The handle of the buffer you want to log the message in, or NULL to use the default buffer that you specified earlier with slog2_set_default_buffer().
code
A user-specified code that you want to be associated with the message. The slog2 system doesn't interpret this code in any way.

  • SLOG2_SHUTDOWN
  • SLOG2_CRITICAL
  • SLOG2_ERROR
  • SLOG2_WARNING
  • SLOG2_NOTICE

  • SLOG2_DEBUG1
  • SLOG2_DEBUG2

format
A printf-formatted character string used to define the log.
arglist
A va_list of the additional arguments required by the format string.
