CeQueryInstructionSet (RAPI) (Windows Embedded CE 6.0)
1/6/2010
The CeQueryInstructionSet function queries a remote Windows Embedded CE-based device to determine whether it supports the specified processor-specific instruction set.
Syntax
BOOL CeQueryInstructionSet(
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. Setting this parameter to PROCESSOR_QUERY_INSTRUCTION causes the device's current instruction set to be returned in the lpdwCurrentInstructionSet parameter. The following table shows the accepted values for this parameter.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 Value
Returns nonzero if the instruction set passed in through dwInstructionSet is supported by the current OS. Otherwise, returns zero.
Returns nonzero if dwInstructionSet is set to PROCESSOR_QUERY_INSTRUCTION. The lpdwCurrentInstructionSet parameter is then set to the current instruction set supported.
Returns zero 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.
