set struct-convention mode ¶Set the convention used by the inferior to return structs and
unions from functions to mode. Possible values of
mode are "pcc", "reg", and "default" (the
default). "default" or "pcc" means that structs
are returned on the stack, while "reg" means that a
struct or a union whose size is 1, 2, 4, or 8 bytes will
be returned in a register.
