It supports multiple * devices and multiple pipes per device. * * The vstusb driver supports two interfaces: * 1 - ioctl SEND_PIPE/RECV_PIPE - a general bulk write/read msg * interface to any pipe with timeout support; * 2 - standard read/write with ioctl config - offers standard read/write * interface with ioctl configured pipes and timeouts. * * Both interfaces can be signal from other process and will abort its i/o * operation. * * A timeout of 0 means NO timeout. The user can still terminate the read via * signal. * * If using multiple threads with this driver, the user should ensure that * any reads, writes, or ioctls are complete before closing the device. * Changing read/write timeouts or pipes takes effect on next read/write. * *****************************************************************************/ struct vstusb_args { union { /* this struct is used for IOCTL_VSTUSB_SEND_PIPE, * * IOCTL_VSTUSB_RECV_PIPE, and read()/write() fops */ struct { void *buffer; size_t count; unsigned int timeout_ms; int pipe; }; /* this one is used for IOCTL_VSTUSB_CONFIG_RW */ struct { int rd_pipe; int rd_timeout_ms; int wr_pipe; int wr_timeout_ms; }; }; }; #define VST_IOC_MAGIC 'L' #define VST_IOC_FIRST 0x20 #define IOCTL_VSTUSB_SEND_PIPE _IO(VST_IOC_MAGIC, VST_IOC_FIRST) #define IOCTL_VSTUSB_RECV_PIPE _IO(VST_IOC_MAGIC, VST_IOC_FIRST + 1) #define IOCTL_VSTUSB_CONFIG_RW _IO(VST_IOC_MAGIC, VST_IOC_FIRST + 2)
