30.Sh NAME
31.Nm dwarf_set_reloc_application
32.Nd set a library-wide relocation flag
33.Sh LIBRARY
34.Lb libdwarf
35.Sh SYNOPSIS
36.In libdwarf.h
37.Ft int
38.Fo dwarf_set_reloc_application
39.Fa "int apply"
40.Fc
41.Sh DESCRIPTION
42Function
43.Fn dwarf_set_reloc_application
44allows applications to specify how relocation information is to be
45handled by the DWARF(3) library.
46.Pp
47If the argument
48.Ar apply
49holds a non-zero value, the library will process all the relevant
50.Dq ".rel"
51and
52.Dq ".rela"
53relocation sections and will apply the relocation records found to
54their corresponding DWARF sections.
55.Pp
56If the argument
57.Ar apply
58is zero, the library will not attempt to apply any relocations.
59.Pp
60The default behaviour of the library is to process relocation records.
61.Sh NOTES
62Function
63.Fn dwarf_set_reloc_application
64should be called before initialising a dwarf debugging context, i.e,
65it should be called by the application before calling either of the
66functions
67.Xr dwarf_init 3
68or
69.Xr dwarf_elf_init 3 .
70.Sh RETURN VALUES
71Function
72.Fn dwarf_set_reloc_application
73returns the previous value of the library-wide relocation application
74flag.
75.Sh ERRORS
76Function
77.Fn dwarf_set_reloc_application
78does not return an error.
