TurnKey LAPP stack Live CD appliance 2008.11.05-hardy-x86 (Default branch)
11-06-2008
TurnKey LAPP stack appliance is an easy-to-use, lightweight, installable live CD of the LAPP stack (Linux, Apache, PostgreSQL, PHP). It can run on real hardware in addition to most types of virtual machines. It features a Mac OS X themed Web management interface and a Python configuration and installation console. It is based on Ubuntu 8.04.1 Hardy LTS, and is designed to provide users with a pre-integrated, automatically updated, turn-key operating system environment that is carefully built from the ground up with the minimum components needed to run the LAPP stack with maximum usability, efficiency, and security. |

STACK(9) BSD Kernel Developer's Manual STACK(9) NAME
STACK -- stack macros SYNOPSIS
#include <sys/param.h> type STACK_ALLOC(sp, size); type STACK_MAX(sp, size); type STACK_ALIGN(sp, bytes); type STACK_GROW(sp, size); type STACK_SHRINK(sp, size); DESCRIPTION
A stack is an area of memory with a fixed origin but with a variable size. A stack pointer points to the most recently referenced location on the stack. Initially, when the stack has a size of zero, the stack pointer points to the origin of the stack. When data items are added to the stack, the stack pointer moves away from the origin. The STACK_ALLOC() macro returns a pointer to allocated stack space of some size. Given the returned pointer sp and size, STACK_MAX() returns the maximum stack address of the allocated stack space. The STACK_ALIGN() macro can be used to align the stack pointer sp by the specified amount of bytes. Two basic operations are common to all stacks: a data item is added (``push'') to the location pointed by sp or a data item is removed (``pop'') from the stack. The stack pointer must be subsequently adjusted by the size of the data item. The STACK_GROW() and STACK_SHRINK() macros adjust the stack pointer sp by given size. A stack may grow either up or down. The described macros take this into account by using the __MACHINE_STACK_GROWS_UP preprocessor define. SEE ALSO
