DWARF_GET_FDE_INSTR_BYTES(3)				   BSD Library Functions Manual 			      DWARF_GET_FDE_INSTR_BYTES(3)

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
     descriptor.

     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.
