vslogf()

Synopsis:

#include <stdio.h>
#include <sys/slog.h>

int vslogf( int opcode,
            int severity, 
            const char * fmt,
            va_list arg );

Since:

BlackBerry 10.0.0

Arguments:

opcode: A combination of a major and minor code. Create the opcode using the _SLOG_SETCODE( major , minor ) macro that's defined in <sys/slog.h>.
The major and minor codes are defined in <sys/slogcodes.h>.
severity: The severity of the log message; see " Severity levels," in the documentation for slogf().
fmt: A standard printf() string.
arg: A variable-argument list of the additional arguments, which you must have initialized with the va_start() macro.

Library:

libc

Use the -l c option to qcc to link against this library. This library is usually included automatically.

Note: This function is in libc.a, but not in libc.so (in order to save space).

Description:

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() .
