DEVICE_GET_SYSCTL(9) BSD Kernel Developer's Manual DEVICE_GET_SYSCTL(9)NAME
device_get_sysctl_ctx, device_get_sysctl_tree -- manipulate the sysctl oid tree for driver specific sysctl nodes
SYNOPSIS
#include <sys/param.h>
#include <sys/bus.h>
struct sysctl_ctx_list *
device_get_sysctl_ctx(device_t dev);
struct sysctl_oid *
device_get_sysctl_tree(device_t dev);
DESCRIPTION
The newbus system automatically adds a sysctl node for each device in the system. This node can be accessed with the
device_get_sysctl_tree() function. The context for the node can be obtained with the device_get_sysctl_ctx() function.

BUS_ADD_CHILD(9) BSD Kernel Developer's Manual BUS_ADD_CHILD(9)NAME
BUS_ADD_CHILD -- add a device node to the tree with a given priority
SYNOPSIS
#include <sys/param.h>
#include <sys/bus.h>
int
BUS_ADD_CHILD(device_t dev, int order, const char *name, int unit);
DESCRIPTION
The BUS_ADD_CHILD() method is used by the driver identify routine to add devices to the tree. Please see device_add_child(9) for more
details. The interface is the same as device_add_child(9) however, the bus' BUS_ADD_CHILD() is called.
Busses implementing BUS_ADD_CHILD() should insert the device into the tree using device_add_child(9) before adding things such as their own
ivars and resource lists to the device.
RETURN VALUES
The BUS_ADD_CHILD() method returns device_t added to the tree, or NULL.

I have seen some misinformation regarding Unix file permissions. I will try to set the record straight. Take a look at this example of some output from ls:

Suppose I have a main() function with only one malloc statement allocating say some 1 gb memory. Also say my system has 1 gb of ram.
main()

malloc(1gb)
return(0)
}
The program above exits without freeing the memory.
In this case will the 1 gb of heap memory be returned... (9 Replies)
I see lot of ad-hoc shell scripts in our servers which don't have a shebang at the beginning .
Does this mean that it will run on any shell ?
Is it a good practice to create scripts (even ad-hoc ones) without shebang ? (16 Replies)
