Use C lib (dll) in java with specific c call convention cdecl -


i working on project have sensors , want them connect pc via usb. write there windows lib written in c , functions using cdecl call convention of c , have sure if programm in other language (java!) call convention given.

so researched bit , found few tutorials bind dlls in java , or use jna. new things me , want sure, possible (and maybe example) - device isn't cheap , want know before buy it.

you can call c code java - there no issues here.

then, if have specific in c routines, can go via wrapper.

take here.

in sample, calling c code - in turn - calls library.

you can linking jni code other library. here:

there plenty of options. when comes jni vs. jna. make sure jna efficient enough. in general, jna tends slower. take here:

hope helps.

i don't post codes here - samples in jni cookbook available github.

inversion of control - Autofac named registration constructor injection -

does autofac support specifying registration name in components' constructors? example: ninject's namedattribute . you need use autofac.extras.attributed package on top achieve this so let's have 1 interface , 2 classes: public interface ihello { string sayhello(); } public class englishhello : ihello { public string sayhello() { return "hello"; } } public class frenchhello : ihello { public string sayhello() { return "bonjour"; } } then have consumer class, in want select instance injected: public class helloconsumer { private readonly ihello helloservice; public helloconsumer([withkey("en")] ihello helloservice) { if (helloservice == null) { throw new argumentnullexception("helloservice"); } this.helloservice = helloservice; } public string sayhello() { return this.helloservice.sayhello()...

verilog - Systemverilog dynamic casting issues -

i've code snippet following in testbench function void write_to_port( my_data_type_base data ); my_data_type_extended data_ext; if(!$cast(data_ext, data)); `uvm_error(get_type_name(), "failed cast"); `uvm_info(get_name(), $psprintf("data_ext :\n%s", data_ext.sprint()), uvm_medium) // write data_ext out port.... endfunction when run it, i'm getting uvm_error "failed cast." i'm not quire sure why $cast not returning 1. can see, i'm printing out extended class data item after casting uvm_info. can see it's being cast properly. if don't use $cast if condition, don't runtime error. isn't coding practice use if dynamic cast check if $cast returning 1 ? what might reason behind cast not returning 1 in above case? i think semicolon on line 'if' not belong? i think consumes if statement, , uvm_error executes regardless of how if evaluates: if(!$cast(data_ext, data)); <- no semico...
