DWARF_GET_FDE_RANGE(3) FreeBSD Library Functions Manual NAME dwarf_get_fde_range - retrieve range information from an FDE descriptor LIBRARY DWARF Access Library (libdwarf, -ldwarf) SYNOPSIS #include <libdwarf.h> int dwarf_get_fde_range(Dwarf_Fde fde, Dwarf_Addr *low_pc, Dwarf_Unsigned *func_len, Dwarf_Ptr *fde_bytes, Dwarf_Unsigned *fde_byte_len, Dwarf_Off *cie_offset, Dwarf_Signed *cie_index, Dwarf_Off *fde_offset, Dwarf_Error *err); DESCRIPTION Function dwarf_get_fde_range() retrieves range and offset information from a given FDE descriptor. Argument fde should reference a valid DWARF FDE descriptor. Argument low_pc should point to a location that will be set to the lowest program counter address covered by the FDE descriptor. Argument func_len should point to a location that will hold the length in bytes of the address range covered by the FDE descriptor. Argument fde_bytes should point to a location that will be set to a pointer to the content of the FDE descriptor itself. Argument fde_byte_len should point to a location that will hold the length in bytes of the FDE descriptor itself. Argument cie_offset should point to a location that will be set to the offset, relative to the DWARF ".debug_frame" section, of the CIE descriptor associated with the given FDE descriptor. Argument cie_index should point to a location that will hold the index of the CIE descriptor associated with the FDE descriptor. The returned value is a zero-based index into the array of CIE descriptors returned by a prior call to functions dwarf_get_fde_list(3) or dwarf_get_fde_list_eh(3). Argument fde_offset should point to a location that will be set to the offset, relative to the DWARF ".debug_frame" section, of the FDE 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_fde_range() 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_fde_range() can fail with: [DW_DLE_ARGUMENT] One of the arguments fde, low_pc, func_len, fde_bytes, fde_byte_len, cie_offset, cie_index or fde_offset was NULL.
