fopen return null and getlasterror return 997(error_io_pending_

Question

I use the fopen(filepath, "rb"), but fopen return NULL,

and GetLastError() return 997 (ERROR_IO_PENDING).

I searched about this problem in google, but i can't find anything.

please help me.

Answer 1

ERROR_IO_PENDING means you can't open the file because it is currently open either for writes or for read in non-shared mode.
