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.
