DWARF_GET_CIE_INFO(3)      Library Functions Manual      DWARF_GET_CIE_INFO(3)

NAME
     dwarf_get_cie_info - retrieve information associated with a CIE
     descriptor

LIBRARY
     DWARF Access Library (libdwarf, -ldwarf)

SYNOPSIS
     #include <libdwarf.h>

     int
     dwarf_get_cie_info(Dwarf_Cie cie, Dwarf_Unsigned *cie_byte_len,
         Dwarf_Small *version, char **augmentation, Dwarf_Unsigned *caf,
         Dwarf_Unsigned *daf, Dwarf_Half *ra, Dwarf_Ptr *init_inst,
         Dwarf_Unsigned *inst_len, Dwarf_Error *err);

DESCRIPTION
     Function dwarf_get_cie_info() retrieves the information associated with a
     given CIE descriptor.

     Argument cie should reference a valid DWARF CIE descriptor, such as would
     be returned by function dwarf_get_cie_of_fde(3).

     Argument cie_byte_len should point to a location that will hold the
     length in bytes of the CIE descriptor itself.

     Argument version should point to a location that will hold the version
     number of the CIE descriptor.

     Arugment augmentation should point to a location that will be set to a
     pointer to a NUL-terminated string containing augmentation data encoded
     as UTF-8.

     Argument caf should point to a location that will hold the code alignment
     factor recorded in the CIE descriptor.

     Arugment daf should point to a location that will hold the data alignment
     factor recorded in the CIE descriptor.

     Argument ra should point to a location that will hold the return address
     recorded in the CIE descriptor.

     Argument init_inst should point to a location that will be set to a
     pointer to an array of bytes containing the initial instructions
     associated with the CIE descriptor.

     Argument inst_len should point to a location that will hold the length in
     bytes of the initial instructions returned in argument init_inst.

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

RETURN VALUES
     Function dwarf_get_cie_info() 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_cie_info() can fail with:

     [DW_DLE_ARGUMENT]       One of the arguments cie, cie_byte_len, version,
                             augmentation, caf, daf, ra, init_inst or inst_len
                             was NULL.
