Description:
|
||
|
|
OS Dependent function declaration. These functions must be implemented for the
|
||
|
|
toolkit, to allow abstraction from the operating system
|
||
|
|
|
||
|
|
Changes:
|
||
|
|
Date Description
|
||
|
|
-----------------------------------------------------------------------------------
|
||
|
|
2022-06-07 Added new option and functions to handle cached IO memory buffers
|
||
|
|
2021-09-01 - updated function parameters to match templates in OS_Custom.c
|
||
|
|
- changed OS-Time() parameters to 64Bit data types
|
||
|
|
2011-11-29 Added OS_Time() function
|
||
|
|
2011-05-25 OS_Init was still using long instead of int32_t as return
|
||
|
|
2010-03-29 Added define CIFX_TOOLKIT_ENABLE_DSR_LOCK to allow lockout against
|
||
|
|
ISR (used in DSR). This needs the functions OS_IrqLock / OS_IrqUnlock
|
||
|
|
which should lock at least against the Device Interrupt
|
||
|
|
2008-06-17 Function OS_MapUserPointer() and OS_UnmapUserPointer() extended by
|
||
|
|
a new parameter pcOSDependent
|
||
|
|
2007-04-19 OS_Strnicmp function included
|
||
|
|
2007-03-27 Mutex functions included
|
||
|
|
2007-03-21 Support enabling and disabling on interrupts on the card (used for assign
|
||
|
|
PCI interrupts and enabling the host to process the DPM/PCI Irqs)
|
||
|
|
2006-07-07 initial version
|
||
|
