Just like |libcall()|, but used for a function that returns an int instead of a string. {only in Win32 on some Unix versions, when the |+libcall| feature is present} Examples: :echo libcallnr("/usr/lib/libc.so", "getpid", "") :call libcallnr("libc.so", "printf", "Hello World!\n") :call libcallnr("libc.so", "sleep", 10) Can also be used as a |method|, the base is passed as the third argument: GetValue()->libcallnr("libc.so", "printf")
