MISC_REGISTER(9)                      Miscellaneous Devices                      MISC_REGISTER(9)



NAME
       misc_register - register a miscellaneous device

SYNOPSIS
       int misc_register(struct miscdevice * misc);

ARGUMENTS
       misc
           device structure

DESCRIPTION
       Register a miscellaneous device with the kernel. If the minor number is set to
       MISC_DYNAMIC_MINOR a minor number is assigned and placed in the minor field of the
       structure. For other cases the minor number requested is used.

       The structure passed is linked into the kernel and may not be destroyed until it has been
       unregistered. By default, an open syscall to the device sets file->private_data to point
       to the structure. Drivers don't need open in fops for this.

       A zero is returned on success and a negative errno code for failure.
