|
*
|
|
* Description:
|
|
* Configure to use the character device (or file) at /dev/console as the
|
|
* SYSLOG channel.
|
|
*
|
|
* This tiny function is simply a wrapper around syslog_dev_initialize()
|
|
* and syslog_channel(). It calls syslog_dev_initialize() to configure
|
|
* the character device at /dev/console then calls syslog_channel() to
|
|
* use that device as the SYSLOG output channel.
|
|
*
|
|
* NOTE interrupt level SYSLOG output will be lost in the general case
|
|
* unless the interrupt buffer is used. As a special case: If the serial
|
|
* console is used and the architecture provides up_putc(), the interrupt
|
|
* level output will be directed to up_putc() is the interrupt buffer is
|
|
* disabled.
|
|
*
|
|
* Input Parameters:
|
|
* None
|
|
*
|
|
* Returned Value:
|
|
* Zero (OK) is returned on success; a negated errno value is returned on
|
|
* any failure.
