DWARF_GET_CIE_OF_FDE(3) 				   BSD Library Functions Manual 				   DWARF_GET_CIE_OF_FDE(3)

NAME

     dwarf_get_cie_of_fde -- retrieve CIE descriptor

LIBRARY

     DWARF Access Library (libdwarf, -ldwarf)

SYNOPSIS

     #include <libdwarf.h>

     int
     dwarf_get_cie_of_fde(Dwarf_Fde fde, Dwarf_Cie *ret_cie, Dwarf_Error *err);

DESCRIPTION

     Function dwarf_get_cie_of_fde() retrieves the CIE descriptor associated with a given FDE descriptor.

     Argument fde should reference a valid FDE descriptor.

     Argument ret_cie should point to a location that will hold the returned CIE 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_cie_of_fde() 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_of_fde() can fail with:

     [DW_DLE_ARGUMENT]	Either of arugments fde or ret_cie was NULL.

DWARF_GET_CIE_INFO(3)					   BSD 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 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.
