NAME
       disassembler - Disassemble a machine instruction and print the results

SYNOPSIS
       int disassembler (
	   unsigned long iadr,
	   int regstyle,
	   char *(*get_symname)(unsigned long address),
	   unsigned long (*get_regvalue)(unsigned regnum),
	   unsigned (*get_bytes)(void),
	   void (*print_header)
		(unsigned long iadr, unsigned instruction) );

PARAMETERS
       Specifies  the  instruction  address to be disassembled.  Specifies how registers are named in the disassembly; if the value is 0, compiler
       names are used; otherwise, hardware names are used.

       The next four arguments are function pointers, most of which give the caller some flexibility in the appearance of  the	disassembly.   The
       only  function  that  must be provided is get_bytes.  All other functions are optional; pass a NULL for each that is not needed.  Is called
       with no arguments and returns the next byte or bytes to disassemble.  Is passed an address, which is the target	of  a  jmp,  jsr,  or  bsr
       instruction.   If NULL is returned or if get_symname is NULL, the disassembler prints the address; otherwise, the string name is printed as
       returned from get_symname.  If not NULL, is passed a register number and returns the current contents of the specified register.  The  dis-
       assembler prints this information along with the instruction disassembly.  If not NULL, is passed the instruction address iadr and the cur-
       rent instruction to be disassembled, which is the return value from get_bytes.  Print_header can use these parameters to print any  desired
       information before the actual instruction disassembly is printed.

DESCRIPTION
       The disassembler disassembles and prints a machine instruction on stdout.

       The program must be linked with the object file access routine library libmld.a.

RETURN VALUES
       If  get_bytes  is  NULL,  the  disassembler returns -1 and errno is set to EINVAL; otherwise, the number of bytes that were disassembled is
       returned.
