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.
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.
dwarf_get_fde_range
() can fail with:
DW_DLE_ARGUMENT
