+.Sh NAME
+.Nm hexdump
+.Nd "Dump a block of bytes to the console in hexidecimal form"
+.Sh SYNOPSIS
+.In sys/systm.h
+.Ft void
+.Fn hexdump "void *ptr" "int length" "const char *hdr" "int flags"
+.Sh DESCRIPTION
+Hexdump prints an array of bytes to the console in hexidecimal form, along with
+the ASCII representation of the bytes, if possible.  By default, each line of
+output will start with an offset count, followed by 16 hexidecimal values,
+followed by 16 ASCII characters.
+.Bl -tag -width 6n
+.It Fa ptr
+Pointer to the array of bytes to print.  It does not need to be NULL-terminated.
+.It Fa length
+Number of bytes to print
+.It Fa hdr
+Pointer to a NULL-terminated character string that will be prepended to each
+line of output.  A value of NULL implies that no header will be printed.
+.It Fa flags
+Flags for controlling the formatting of the output
+.Bl -tag -width HD_OMIT_COUNT
+.It Fa Bits 0-7
+Integer value of the number of bytes to display on each line.  A value of 0
+implies that the default value of 16 will be used.
+.It Fa Bits 8-15
+Character ASCII value to use as the separator for the hexidecimal output.  A
+value of 0 implies that the default value of 32 (ASCII space) will be used.
+.It Fa HD_OMIT_COUNT
+Don't print the offset column at the beginning of each line
+.It Fa HD_OMIT_HEX
+Don't print the hexidecimal values on each line.
+.It Fa HD_OMIT_CHARS
+Don't print the character values on each line.
