print

print(9E)							Driver Entry Points							 print(9E)

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.
