45.Sh DESCRIPTION
46The function
47.Fn dwarf_producer_set_isa
48sets the instruction set architecture for a DWARF producer instance.
49.Pp
50Argument
51.Ar dbg
52should reference a DWARF producer instance allocated using one of
53the functions
54.Xr dwarf_producer_init 3
55or
56.Xr dwarf_producer_init_b 3 .
57.Pp
58Argument
59.Ar isa
60specifies the desired instruction set architecture.
61Legal values for this argument are those defined by the
62.Vt "enum Dwarf_ISA"
63enumeration defined in the header file
64.In libdwarf.h .
65.Pp
66If the argument
67.Ar err
68is not NULL, it will be used to store error information in case of an
69error.
70.Sh COMPATIBILITY
71The
72.Fn dwarf_producer_set_isa
73function is a local extension.
74.Sh RETURN VALUES
75On success, the function
76.Fn dwarf_producer_set_isa
77returns
78.Dv DW_DLV_OK .
79In case of an error, this function returns
80.Dv DW_DLV_ERROR
81and sets the argument
82.Ar err .
83.Sh ERRORS
84The
85.Fn dwarf_producer_set_isa
86function can fail with:
87.Bl -tag -width ".Bq Er DW_DLE_ARGUMENT"
88.It Bq Er DW_DLE_ARGUMENT
89The argument
90.Ar dbg
91was NULL.
92.It Bq Er DW_DLE_ARGUMENT
93The argument
94.Ar isa
95was invalid.
