EnumPageFilesW function (psapi.h)
Calls the callback routine for each installed pagefile in the system.
Syntax
BOOL EnumPageFilesW(
[out] PENUM_PAGE_FILE_CALLBACKW pCallBackRoutine,
[in] LPVOID pContext
);
Parameters
[out] pCallBackRoutine
A pointer to the routine called for each pagefile. For more information, see EnumPageFilesProc.
[in] pContext
The user-defined data passed to the callback routine.
Return value
If the function succeeds, the return value is TRUE. If the function fails, the return value is FALSE. To get extended error information, call GetLastError.
Remarks
Starting with Windows 7 and Windows Server 2008 R2, Psapi.h establishes version numbers for the PSAPI functions. The PSAPI version number affects the name used to call the function and the library that a program must load.
If PSAPI_VERSION is 2 or greater, this function is defined as K32EnumPageFiles in Psapi.h and exported in Kernel32.lib and Kernel32.dll. If PSAPI_VERSION is 1, this function is defined as EnumPageFiles in Psapi.h and exported in Psapi.lib and Psapi.dll as a wrapper that calls K32EnumPageFiles.
Programs that must run on earlier versions of Windows as well as Windows 7 and later versions should always call this function as EnumPageFiles. To ensure correct resolution of symbols, add Psapi.lib to the TARGETLIBS macro and compile the program with –DPSAPI_VERSION=1. To use run-time dynamic linking, load Psapi.dll.
Note
The psapi.h header defines EnumPageFiles as an alias which automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. Mixing usage of the encoding-neutral alias with code that not encoding-neutral can lead to mismatches that result in compilation or runtime errors. For more information, see Conventions for Function Prototypes.
