54 retrieves range and offset information from a given FDE descriptor.
58 should reference a valid DWARF FDE descriptor.
62 should point to a location that will be set to the lowest
63 program counter address covered by the FDE descriptor.
67 should point to a location that will hold the length in bytes of
68 the address range covered by the FDE descriptor.
72 should point to a location that will be set to a pointer to the
73 content of the FDE descriptor itself.
77 should point to a location that will hold the length in bytes of
78 the FDE descriptor itself.
82 should point to a location that will be set to the offset, relative to
85 section, of the CIE descriptor associated with the given FDE
90 should point to a location that will hold the index of the CIE
91 descriptor associated with the FDE descriptor.
92 The returned value is a zero-based index into the array of CIE
93 descriptors returned by a prior call to functions
94 .Xr dwarf_get_fde_list 3
96 .Xr dwarf_get_fde_list_eh 3 .
100 should point to a location that will be set to the offset, relative to
103 section, of the FDE descriptor.
107 is not NULL, it will be used to store error information in case of an
