52 retrieves range and offset information from a given FDE descriptor.
56 should reference a valid DWARF FDE descriptor.
60 should point to a location that will be set to the lowest
61 program counter address covered by the FDE descriptor.
65 should point to a location that will hold the length in bytes of
66 the address range covered by the FDE descriptor.
70 should point to a location that will be set to a pointer to the
71 content of the FDE descriptor itself.
75 should point to a location that will hold the length in bytes of
76 the FDE descriptor itself.
80 should point to a location that will be set to the offset, relative to
83 section, of the CIE descriptor associated with the given FDE
88 should point to a location that will hold the index of the CIE
89 descriptor associated with the FDE descriptor.
90 The returned value is a zero-based index into the array of CIE
91 descriptors returned by a prior call to functions

98 should point to a location that will be set to the offset, relative to
