BUS_SET_PASS(9) BSD Kernel Developer's Manual BUS_SET_PASS(9)NAME
bus_set_pass -- raise the bus pass level
SYNOPSIS
#include <sys/param.h>
#include <sys/bus.h>
void
bus_set_pass(int pass);
DESCRIPTION
The bus_set_pass function is called during boot to raise the bus pass level to pass. The function will rescan the device tree for each pass
level between the current pass level and the new level that has at least one associated driver. The device tree rescans are implemented by
invoking the BUS_NEW_PASS(9) method on the root bus device.

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.

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)
