.Sh DESCRIPTION
|
|
The
|

.Fn hexdump
|
|
function prints an array of bytes to standard out in hexadecimal form,

|
along with the
|
|
.Tn ASCII
|
|
representation of the bytes, if possible.
|
|
By default, each line of
|
|
output will start with an offset count, followed by 16 hexadecimal values,
|
|
followed by 16
|
|
.Tn ASCII
|
|
characters.
|
|
.Bl -tag -width indent
|
|
.It Fa ptr
|

Pointer to the array of bytes to print.

-terminated.
|
|
.It Fa length
|
|
Number of bytes to print.
|
|
.It Fa hdr
|
|
Pointer to a

|
.Dv NUL Ns
|
|
-terminated character string that will be prepended to each

.Dv NULL
|
|
implies that no header will be printed.

|
Flags for controlling the formatting of the output.
|
|
.Bl -tag -width ".Dv HD_OMIT_COUNT"
|
|
.It 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 Bits 8-15
|
|
Character
|
|
.Tn ASCII
|
|
value to use as the separator for the hexadecimal output.
|
|
A value of 0 implies that the default value of 32
|
|
.Tn ( ASCII
|
|
space) will be used.
|
|
.It Dv HD_OMIT_COUNT
|
|
Do not print the offset column at the beginning of each line.
|
|
.It Dv HD_OMIT_HEX
