DWARF_GET_FDE_INSTR_B... BSD Library Functions Manual DWARF_GET_FDE_INSTR_B... 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.
