_IOW and friends, defined in <sys/ioccom.h>, help build ioctl() calls. Is there an equivalent function in Swift?
Is there a Swift function for the _IOW macro?
Is there an equivalent function in Swift?
No.
I’ve never actually filed a bug about this, because I’ve always kinda hoped that the Swift importer will get smart enough to handle it. Sadly, that’s not panned out yet.
I generally get around this by doing the ioctl in C code and then calling that C code from Swift.
Share and Enjoy
