    2525The '''dev_fbf_init()''' function makes two initializations :
    2626 * it completes the FBF specific fields of the chdev descriptor.
    27  * It calls the ''fbf_driver_init() function, to initialise the specific hardware device, when required.
     27 * It calls the ''fbf_driver_init()'' function, to initialise the specific hardware device, when required.
    2828It must be called by a local thread.

    3636This function implements the ''fbf_get_config()'' syscall. It returns the FBF number of lines, the number of pixels per line, and the pixel encoding type. It can be called by a client thread running in any cluster.
    37 It does not access the hardware, as the size and type have been registered in the chdev descriptor extension by the dev_fbf_init() function.
     37It does not access the hardware, as these informations have been registered in the chdev descriptor extension by the ''dev_fbf_init()'' function.
