应用层怎么读取驱动下的数据

ckf513728912

如题
int usb_get_string_simple(usb_dev_handle *dev, int index, char *buf, size_t buflen);

我怎么把chr *buf数据读到应用层

我想把usb驱动读出usb设备的名字传入到应用层　　然后在应用层把usb设备名字显示出来，或者用哪个函数能读取usb设备名字　谢谢大家


retval = FindToken((unsigned char*)iBuf,&count);  　会调用

unsigned long  et_FindToken(unsigned char* pid, int * count){
~~~~~~~~~~~~~~~~~~~~~~~~~~
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
~~~~~~~~~~~~~~~~~~~~~~~~~
return  Find(Char2ByteOldPid, count);      
}


Find会调用
unsigned long Find(unsigned char* pid , int * count){
char            sbuffer[1024];
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
retcode = usb_get_string_simple(usbhandle, dev->descriptor.iProduct, sbuffer, sizeof(sbuffer));  
printf("usb  name: %s\n", sbuffer);
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
}


想应用层sbuffer为usb名字
printf("Find %ld %s.\n",count, sbuffer);
