QueryInstructionSet (Windows CE 5.0)
This function queries to determine what instruction set is supported in the OS.
BOOL QueryInstructionSet(DWORD dwInstructionSet,LPDWORD lpdwCurrentInstructionSet);
Parameters
- dwInstructionSet
[in] The instruction set that will be queried to determine if it is supported by the currently running OS. The following table shows the acceptable values.Value Description Floating point hardware Floating point emulation PROCESSOR_X86_32BIT_INSTRUCTION 32bit x86. Yes Yes PROCESSOR_MIPS_MIPS16_INSTRUCTION MIPS16 instruction set. No Yes PROCESSOR_MIPS_MIPSII_INSTRUCTION MIPS II instruction set. No Yes PROCESSOR_MIPS_MIPSIIFP_INSTRUCTION MIPS II instruction set. Yes No PROCESSOR_MIPS_MIPSIV_INSTRUCTION MIPS IV instruction set. No Yes PROCESSOR_MIPS_MIPSIVFP_INSTRUCTION MIPS IV instruction set. Yes No PROCESSOR_HITACHI_SH3_INSTRUCTION Hitachi SH3 instruction set. No Yes PROCESSOR_HITACHI_SH3DSP_INSTRUCTION Hitachi SH3 instruction set with built-in digital signal processor (DSP). No No PROCESSOR_HITACHI_SH4_INSTRUCTION Hitachi SH4 instruction set. Yes No PROCESSOR_ARM_V4_INSTRUCTION ARM V4 instruction set. No Yes PROCESSOR_ARM_V4FP_INSTRUCTION ARM V4 instruction set. Yes No PROCESSOR_ARM_V4I_INSTRUCTION ARM V4 with Thumb instruction set. No Yes PROCESSOR_ARM_V4IFP_INSTRUCTION ARM V4 with Thumb instruction set. Yes No PROCESSOR_ARM_V4T_INSTRUCTION ARM V4 with Thumb instruction set. No Yes PROCESSOR_ARM_V4TFP_INSTRUCTION ARM V4 with Thumb instruction set. Yes No PROCESSOR_QUERY_INSTRUCTION Request to have the current instruction set reported to the caller. No No - lpdwCurrentInstructionSet
[out] Returns the current instruction set supported by the OS.
Return Values
Returns TRUE if the instruction set passed in through dwInstructionSet is supported by the current OS. Otherwise, returns FALSE.
Returns TRUE if dwInstructionSet is set to PROCESSOR_QUERY_INSTRUCTION. The lpdwCurrentInstructionSet parameter is then set to the current instruction set supported.
Returns FALSE if the dwInstructionSet value is unknown.
Remarks
This function can be used by any application that needs to determine if the code about to install or run will work on the current OS. The OS knows explicitly what instruction it will execute, and therefore will inform you if your installation should continue.
