DWARF_GET_FDE_N(3)         Library Functions Manual         DWARF_GET_FDE_N(3)

NAME
     dwarf_get_fde_n -- retrieve FDE descriptor

LIBRARY
     DWARF Access Library (libdwarf, -ldwarf)

SYNOPSIS
     #include <libdwarf.h>

     int
     dwarf_get_fde_n(Dwarf_Fde *fdelist, Dwarf_Unsigned fde_index,
         Dwarf_Fde *ret_fde, Dwarf_Error *err);

DESCRIPTION
     Function dwarf_get_fde_n() retrieves an FDE descriptor from an array of
     FDE descriptors.

     Argument fdelist should point to an array of FDE descriptors, as returned
     by the functions dwarf_get_fde_list(3) or dwarf_get_fde_list_eh(3).

     Argument fde_index specifies the 0-based index of the desired FDE
     descriptor.

     Argument ret_fde should point to a location that will hold the returned
     FDE descriptor.

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

RETURN VALUES
     Function dwarf_get_fde_n() returns DW_DLV_OK when it succeeds.  It
     returns DW_DLV_NO_ENTRY if the FDE descriptor index specified by argument
     fde_index is out of range.  In case of an error, it returns DW_DLV_ERROR
     and sets the argument err.

ERRORS
     Function dwarf_get_fde_n() can fail with:

     [DW_DLE_ARGUMENT]       Either of the arguments fdelist or ret_fde was
                             NULL.

     [DW_DLE_NO_ENTRY]       The FDE descriptor index specified by argument
                             fde_index was out of range.
