Function linuxcnc_hal_sys::rtapi_print

pub unsafe extern "C" fn rtapi_print(fmt: *const c_char, ...)

'rtapi_print()' prints a printf style message. Depending on the RTOS and whether the program is being compiled for user space or realtime, the message may be printed to stdout, stderr, or to a kernel message log, etc. The calling syntax and format string is similar to printf except that floating point and longlongs are NOT supported in realtime and may not be supported in user space. For some RTOS's, a 80 byte buffer is used, so the format line and arguments should not produce a line more than 80 bytes long. (The buffer is protected against overflow.) Does not block, but can take a fairly long time, depending on the format string and OS. May be called from user, init/cleanup, and realtime code.
