CeQueryInstructionSet (RAPI) (Compact 7)

  • Article

3/12/2014

The CeQueryInstructionSet function queries a remote Windows Embedded Compact-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.

    Note

    ARMv4, V4FP, V4I, V41FP, V4T, and V4TFP architectures are not supported in Windows Embedded Compact 7.

    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.
