The FsRtlFastCheckLockForWrite routine determines whether the specified process has write access to a locked byte range of a file.
FileLock [in]A pointer to the FILE_LOCK structure for the file. This structure must have been initialized by a previous call to FsRtlAllocateFileLock or FsRtlInitializeFileLock.
StartingByte [in]A pointer to a variable that specifies the starting byte offset within the file of the byte range to check.
Length [in]A pointer to a variable that specifies the length, in bytes, of the range to check.
Key [in]The key for the byte range lock.
FileObject [in]A pointer to the file object for the file.
ProcessId [in]A pointer to the EPROCESS for the process.
The FsRtlFastCheckLockForWrite routine returns TRUE if the specified process has write access, FALSE otherwise.
