Hi,
I can't figure out how to set function pointers to functions defined in a
library. I'm doing the following:
I've an instrument structure which has a member
void (*out)(int instr_nr, int data_type);
When the function pointer is initialized in the standard way:
instr-> out = set_instrument;
and I call instr->out(nr, kINT32);
It works when set_instrument is defined in a c file which is part of the
project.
I would like to put all these instrument C files in one generated library
instruments.lib but this creates several problems.
When I use LoadExternalModule("instruments.lib") and
instr-> out = GetExternalModuleAddr (module_id, "set_instrument", &status);
I see that the function pointer is initialized (no error), but the call to
instr-> out crashes.
Using __stdcall before the set_instrument creates problems when
initializing; well, don't know how to force the function pointer in the cvi
compiler to recognize this with whatever linker option.
instr-> out = __stdcall set_instrument doesn't work.
Any ideas how to do this?
