43.Sh DESCRIPTION
44The function
45.Fn dwarf_producer_set_isa
46sets the instruction set architecture for a DWARF producer instance.
47.Pp
48Argument
49.Ar dbg
50should reference a DWARF producer instance allocated using one of
51the functions
52.Xr dwarf_producer_init 3
53or
54.Xr dwarf_producer_init_b 3 .
55.Pp
56Argument
57.Ar isa
58specifies the desired instruction set architecture.
59Legal values for this argument are those defined by the
60.Vt "enum Dwarf_ISA"
61enumeration defined in the header file
62.In libdwarf.h .
63.Pp
64If the argument
65.Ar err
66is not NULL, it will be used to store error information in case of an
67error.
68.Sh RETURN VALUES
69On success, the function
70.Fn dwarf_producer_set_isa
71returns
72.Dv DW_DLV_OK .
73In case of an error, this function returns
74.Dv DW_DLV_ERROR
75and sets the argument
76.Ar err .
77.Sh COMPATIBILITY
78The
79.Fn dwarf_producer_set_isa
80function is a local extension.
81.Sh ERRORS
82The
83.Fn dwarf_producer_set_isa
84function can fail with:
85.Bl -tag -width ".Bq Er DW_DLE_ARGUMENT"
86.It Bq Er DW_DLE_ARGUMENT
87The argument
88.Ar dbg
89was NULL.
90.It Bq Er DW_DLE_ARGUMENT
91The argument
92.Ar isa
93was invalid.
