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. +.El +.El +.Pp +.Sh SEE ALSO +.Xr ascii 7 +.Sh AUTHORS +This man page was written by +.An Scott Long . |
