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"

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 ".rela"
51relocation sections and will apply the relocation records found to
52their corresponding DWARF sections.
53.Pp
54If the argument
55.Ar apply
56is zero, the library will not attempt to apply any relocations.
57.Pp
58The default behaviour of the library is to process relocation records.
59.Sh NOTES
60Function
61.Fn dwarf_set_reloc_application
62should be called before initialising a dwarf debugging context, i.e,
63it should be called by the application before calling either of the
64functions
65.Xr dwarf_init 3
66or
67.Xr dwarf_elf_init 3 .
68.Sh RETURN VALUES
69Function
70.Fn dwarf_set_reloc_application
71returns the previous value of the library-wide relocation application
72flag.
73.Sh ERRORS
74Function
75.Fn dwarf_set_reloc_application
76does not return an error.
