    NAME

    hexdump
    
     - dump a block of bytes to the console in hexadecimal form
    
     
    

    SYNOPSIS

       #include <sys/systm.h>
    void hexdump (void *ptr int length const char *hdr int flags);
     

    DESCRIPTION

    The hexdump ();
    function prints an array of bytes to the console in hexadecimal 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 hexadecimal values, followed by 16 ASCII characters.

    Fa ptr
    Pointer to the array of bytes to print. It does not need to be NUL -terminated.
    Fa length
    Number of bytes to print.
    Fa hdr
    Pointer to a NUL -terminated character string that will be prepended to each line of output. A value of NULL implies that no header will be printed.
    Fa flags
    Flags for controlling the formatting of the output.

    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.
    Bits 8-15
    Character ASCII value to use as the separator for the hexadecimal output. A value of 0 implies that the default value of 32 ( ASCII space) will be used.
    HD_OMIT_COUNT
    Do not print the offset column at the beginning of each line.
    HD_OMIT_HEX
    Do not print the hexadecimal values on each line.
    HD_OMIT_CHARS
    Do not print the character values on each line.
