DWARF_GET_FDE_INSTR... FreeBSD Library Functions Manual	DWARF_GET_FDE_INSTR...

NAME
     dwarf_get_fde_instr_bytes -- retrieve instructions	from FDE descritpor

LIBRARY
     DWARF Access Library (libdwarf, -ldwarf)

SYNOPSIS
     #include <libdwarf.h>

     int
     dwarf_get_fde_instr_bytes(Dwarf_Fde fde, Dwarf_Ptr	*ret_inst,
	 Dwarf_Unsigned	*ret_len, Dwarf_Error *error);

DESCRIPTION
     Function dwarf_get_fde_instr_bytes() retrieves instruction	bytes from a
     given FDE descriptor.

     Argument fde should reference a valid DWARF FDE descriptor.

     Argument ret_inst should point to a location that will be set to a
     pointer to	an array of bytes containing the instructions of the FDE de-
     scriptor.

     Argument ret_len should point to a	location that will hold	the length in
     bytes of the instructions returned	in argument ret_inst.

     If	argument err is	not NULL, it will be used to store error information
     in	case of	an error.

     Applications can use the function dwarf_expand_frame_instructions(3) to
     parse and expand the returned instruction bytes into an array of
     Dwarf_Frame_Op descriptors.

RETURN VALUES
     Function dwarf_get_fde_instr_bytes() returns DW_DLV_OK when it succeeds.
     In	case of	an error, it returns DW_DLV_ERROR and sets the argument	err.

ERRORS
     Function dwarf_get_fde_instr_bytes() can fail with:

     [DW_DLE_ARGUMENT]	One of the arguments fde, ret_inst or ret_len was
			NULL.
