The %ioctl() function is a general purpose control function that passes the arguments request and arg to the device designated by file.descriptor.
Syntax
var = %ioctl(file.descriptor, request, arg) |
Description
The format of the arguments is device-specific. These arguments are usually binary data that must be kept out of FlashBASIC data space. See the example below.
CAUTION |
Extreme care must be exercised when using this function. The arguments to %ioctl() are dependent on the system and the UNIX version. Whenever possible, it is preferable to use the D3 tools to access a device. For example, execute set-baud /dev/tty15,9600 works on all Pick implementations, while the corresponding UNIX ioctl() function varies widely. |
Example(s)
* Allocate some data ptr=(char*)%malloc(128) * Open the terminal and get its termio structure execute "!exec tty" capturing ttyname fd=%open(ttyname, o$rdwr) n=%ioctl(fd, tcgeta, (char*)ptr) ... * Release data %free((char*) ptr) |
