CeFindFirstFile (RAPI)

  • 项目

This function searches a directory for a file whose name matches the specified filename. CeFindFirstFile examines subdirectory names as well as filenames.

CeFindFirstFile is a remote application interface (RAPI), which enables an application running on a desktop computer to make function calls on a Windows CE–based device.

HANDLE CeFindFirstFile(
LPCWSTR lpFileName, 
LPCE_FIND_DATA lpFindFileData);

Parameters

  • lpFileName
    [in] Long pointer to a null-terminated string that specifies a valid directory or path and filename, which can contain wildcard characters (* and ?).

    There is a default string size limit for paths of MAX_PATH characters. This limit is related to how the FindFirstFile function parses paths. An application can transcend this limit and send in paths longer than MAX_PATH characters prepending "\\?\" to the path. The "\\?\" tells the function to turn off path parsing; it lets paths longer than MAX_PATH be used with FindFirstFile. However, each component in the path cannot be more than MAX_PATH characters long. This also works with Universal Naming Convention (UNC) names. The "\\?\" is ignored as part of the path. For example, "\\?\C:\myworld\private" is seen as "C:\myworld\private" and "\\?\UNC\bill_g_1\hotstuff\coolapps" is seen as "\\bill_g_1\hotstuff\coolapps."

  • lpFindFileData
    [out] Long pointer to the WIN32_FIND_DATA structure that receives information about the found file or subdirectory.

Return Values

A search handle, used in a subsequent call to CeFindNextFile or CeFindClose, indicates success. INVALID_HANDLE_VALUE indicates failure. To determine if a function failed because of RAPI errors, call CeRapiGetError. To determine if a function failed because of non-RAPI errors, call CeGetLastError.

Remarks

When writing applications for Windows CE versions 1.0 and 1.01, use the PegFindFirstFile function.
