NetBSD 6.1.5 - man page for cpu_dumpsize (netbsd section 9)

CPU_DUMPCONF(9) 		  BSD Kernel Developer's Manual 		  CPU_DUMPCONF(9)

NAME
     cpu_dumpconf, cpu_dump, cpu_dumpsize, dumpsys -- machine-dependent kernel core dumps

SYNOPSIS
     #include <sys/types.h>
     #include <sys/systm.h>

     void
     cpu_dumpconf(void);

     int
     cpu_dump(int (*dump)(dev_t, daddr_t, void *, size_t), daddr_t *blknop);

     int
     cpu_dumpsize(void);

     void
     dumpsys(void);

DESCRIPTION
     cpu_dumpconf() is the machine-dependent interface invoked during system bootstrap to deter-
     mine the dump device and initialize machine-dependent kernel core dump state.  Internally,
     cpu_dumpconf() will invoke cpu_dumpsize() to calculate the size of machine-dependent kernel
     core dump headers.

     dumpsys() is invoked by cpu_reboot() to dump kernel physical memory onto the dump device.
     dumpsys() invokes cpu_dump() to write the machine-dependent header to the dump device at
     block number *blknop using the dump device's PIO dump routine specified by the dump argu-
     ment.

     cpu_dumpsize(), cpu_dump(), and dumpsys() are parts of the machine-dependent interface, how-
     ever they are not exported to machine-independent code.
