Function Documentation

struct tty_driver* __tty_alloc_driver ( unsigned int  lines, struct module *  owner, unsigned long  flags  )

read

__tty_alloc_driver – allocate tty driver : count of lines this driver can handle at most : module which is repsonsible for this driver : some of TTY_DRIVER_* flags, will be set in driver->flags

This should not be called directly, some of the provided macros should be used instead. Use IS_ERR and friends on
