overview
The purpose of this page is to give a specification of a FPC feature allowing writing (Linux) kernel modules using FPC. The main purpose is to an easy syntax hiding all the details of sectioning and linking. The ultimate goal of these wiki pages is to provide a proposal for a future support of natural linux kernel module support in particular and driver support in general (for win32...) A dedicated page module language feature is intended to provide specification for this future support.
Language enhancement
This proposal is based on adding a new keyword module triggering a special linking mechanism. Please note that this keyword module is already recognized by GPC for other purpose. The easiest way to illustrate this is using the following example
module kpmod; uses unit1, unit2,...unitn; const MODULE_NAME = 'kpmod'; type TType = some type; const aConst = a value; initialization {Module initialization code} printk(KERN_INFO + 'Module "%s" is being loaded'#10, MODULE_NAME); finalization {Module cleanup code} printk(KERN_INFO + 'Module "%s" is being unloaded'#10, MODULE_NAME); end.
