RTKernel-32 ConfigurationSome of the kernel's configuration parameters are stored in the global structure RTK32Config with the following layout:
typedef struct {
int StructureSize;
DWORD DriverFlags;
DWORD UserDriverFlags;
DWORD Flags;
DWORD DefaultTaskStackSize;
DWORD DefaultIntStackSize;
unsigned MainPriority;
unsigned DefaultPriority;
DWORD HookedIRQs;
DWORD TaskStackOverhead;
RTKDuration TimeSlice;
DWORD IdleTaskStackSize;
} RTK32Config;
A default version of this structure is included in the RTKernel-32 library. If you want to define your own configuration, include this structure in your program or modify selected values before RTKernelInit is called. Example:
RTK32Config RTKConfig = {
sizeof(RTK32Config), // StructureSize
#if MP
DF_IDLE_HALT | // DriverFlags (MP kernel)
#endif
0, // DriverFlags
0, // UserDriverFlags
#if MP
RF_PREEMPTIVE | // MP kernel defaults to preemptive
#endif
#if DEBUG
RF_TCPUTIME | RF_STACKCHECKS | RF_TRACE |
#endif
RF_AUTOINIT | RF_NAMED_WIN32CS,// Flags
16*1024, // DefaultTaskStackSize
#if MP
1024, // DefaultIntStackSize
#else
512, // DefaultIntStackSize
#endif
5, // MainPriority
0, // DefaultPriority
0, // HookedInterrupts (none)
256, // TaskStackOverhead
0, // TimeSlice (0 == off)
256 // IdleTaskStackSize
} ;
The example given above corresponds to RTKernel-32's defaults. For the multiprocessor kernel, preprocessor symbol MP is defined, DEBUG is defined for the Debug Version. Unlike the single processor kernel, the multiprocessor kernel has DriverFlags DF_IDLE_HALT and Flags RF_PREEMPTIVE set and uses a default interrupt stack size of 1024 bytes. You can modify parts of RTKConfig at run time. However, care must be taken not to change them after RTKernel-32 has read and used them. Most values should only be changed before RTKernelInit is called. The various fields of RTK32Config are described below.
