disassembler(3)
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
  iadr
      Specifies the instruction address to be disassembled.

  regstyle
      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.

  get_bytes
      Is called with no arguments and returns the next byte or bytes to
      disassemble.

  get_symname
      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() routine prints the address; otherwise, the string name
      is printed as returned from get_symname.

  get_regvalue
      If not NULL, is passed a register number and returns the current
      contents of the specified register. The disassembler() routine prints
      this information along with the instruction disassembly.

  print_header
      If not NULL, is passed the instruction address iadr and the current
      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() routine 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() routine returns -1 and errno is
  set to EINVAL; otherwise, the number of bytes that were disassembled is
  returned.
