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 associ-
     ated 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.
