NAME

print - display a driver message on system console
 

SYNOPSIS

#include <sys/types.h>
#include <sys/errno.h>
#include <sys/ddi.h>
#include <sys/sunddi.h>



int prefixprint(dev_t dev, char *str);

INTERFACE LEVEL

Architecture independent level 1 (DDI/DKI). This entry point is required for block devices.  

PARAMETERS

dev

Device number.

str

Pointer to a character string describing the problem.

DESCRIPTION

The print() routine is called by the kernel when it has detected an exceptional condition (such as out of space) in the device. To display the message on the console, the driver should use the cmn_err(9F) kernel function. The driver should print the message along with any driver specific information.  

RETURN VALUES

The print() routine should return 0 for success, or the appropriate error number. The print routine can fail if the driver implemented a non-standard print() routine that attempted to perform error logging, but was unable to complete the logging for whatever reason.
