NAME

devfs_get_handle - Find the handle of a devfs entry.

SYNOPSIS

devfs_handle_t devfs_get_handle (devfs_handle_t dir, const char *name, unsigned int major, unsigned int minor, char type, int traverse_symlinks);

ARGUMENTS

dir: The handle to the parent devfs directory entry. If this is NULL the name is relative to the root of the devfs.
name: The name of the entry.
major: The major number. This is used if name is NULL.
minor: The minor number. This is used if name is NULL.
type: The type of special file to search for. This may be either DEVFS_SPECIAL_CHR or DEVFS_SPECIAL_BLK.
traverse_symlinks: If TRUE then symlink entries in the devfs namespace are traversed. Symlinks pointing out of the devfs namespace will cause a failure. Symlink traversal consumes stack space.

DESCRIPTION

Returns a handle which may later be used in a call to devfs_unregister, devfs_get_flags, or devfs_set_flags. A subsequent devfs_put is required to decrement the refcount. On failure NULL is returned.
