+.Sh NAME
+.Nm kvm_dump_mkheader ,
+.Nm kvm_dump_wrtheader ,
+.Nm kvm_dump_inval
+.Nd crash-dump support functions
+.Sh SYNOPSIS
+.Fd #include <kvm.h>
+.br
+.Ft int
+.Fn kvm_dump_mkheader "kvm_t *kd" "off_t dump_off"
+.Ft int
+.Fn kvm_dump_wrtheader "kvm_t *kd" "FILE *fp" "int dumpsize"
+.Ft int
+.Fn kvm_dump_inval "kvm_t *kd"
+.Sh DESCRIPTION
+First note that the functions described here were designed to be used by
+.Xr savecore 8 .
+.Pp
+The function
+.Fn kvm_dump_mkheader
+checks if the physical memory file associated with
+.Fa kd
+contains a valid crash-dump header as generated by a dumping kernel. When a
+valid header is found,
+.Fn kvm_dump_mkheader
+initializes the internal kvm data structures as if a crash-dump generated by
+the
+.Xr savecore 8
+program was opened. This has the intentional side effect of enabling the
+address translation machinery.
+.Pp
+A call to
+.Fn kvm_dump_mkheader
+will most likely be followed by a call to
+.Fn kvm_dump_wrtheader .
+This function takes care of generating the generic header, the CORE_CPU
+section and the section header of the CORE_DATA section. The data is written
+to the file pointed at by
+.Fa fp .
+The
+.Fa dumpsize
+argument is only used to properly the set the segment size of the CORE_DATA
+section. Note that this function assumes that
+.Fa fp
+is positioned at file location 0. This function will not seek and therefore
+allows
+.Fa fp
+to be a file pointer obtained by
+.Fn zopen .
+.Pp
+The
+.Fn kvm_dump_inval
+function clears the magic number in the physical memory file associated with
+.Fa kd .
+The address translations must be enabled for this to work (thus assuming
+that
+.Fn kvm_dum_mkheader
+was called earlier in the sequence).
+.Sh RETURN VALUES
+All functions return 0 on success, -1 on failure. In the case of failure,
+.Xr kvm_geterr 3
+can be used to retrieve the cause of the error.
+.Sh HISTORY
+These functions first appeared in NetBSD 1.1A.
+.Sh BUGS
+There probably are...
