     dwarf_add_frame_cie - add a call frame common information entry to a
     DWARF producer instance

     DWARF Access Library (libdwarf, -ldwarf)

     #include <libdwarf.h>

     dwarf_add_frame_cie(Dwarf_P_Debug dbg, char *augmenter, Dwarf_Small caf,
         Dwarf_Small daf, Dwarf_Small ra, Dwarf_Ptr initinst,
         Dwarf_Unsigned initlen, Dwarf_Error *err);

     Function dwarf_add_frame_cie() adds a DWARF call frame common information
     entry (CIE) to a producer instance.

     Argument dbg should reference a DWARF producer instance allocated using
     dwarf_producer_init(3) or dwarf_producer_init_b(3).

     Argument augmenter should point to a NUL-terminated augmentation string
     for the common information entry.

     Argument caf specifies the code alignment factor.

     Argument daf specifies the data alignment factor.

     Argument ra specifies the column number used for the return address

     Argument initinst should point to a byte stream containing the initial
     instructions for the common information entry.

     Argument initlen should hold the length in bytes of the byte stream
     pointed to by argument initinst.

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

     On success, function dwarf_add_frame_cie() returns the index value of the
     created common information entry.  In case of an error, function
     dwarf_add_frame_cie() returns DW_DLV_NOCOUNT and sets the argument err.

     Function dwarf_add_frame_cie() can fail with:

     [DW_DLE_ARGUMENT]       Argument dbg was NULL.

     [DW_DLE_MEMORY]         An out of memory condition was encountered during
                             the execution of the function.
