Iostream Read From File C Stack Overflow There is only workaround for the issue you are facing. check whether file id in process before starting the process of copy. you can call the following function until you get the false value. 1st method, copied directly from this answer: filestream stream = null; try . stream = file.open(filemode.open, fileaccess.readwrite, fileshare.none);.

C Wait Until Doesn T Seem To Be Waiting Correctly Stack Overflow The main goal is to wait for a file to be accessible (read: waiting until the file lock releases), since it seems like there's no way to do this built into the framework i've written a quick and dirty function to do this. One possible solution would be to have another notifyfilter which could trigger the filesystemwatcher event once the file had been fully written to; or once locks were removed. This example demonstrates how to wait until a file is completely written by attempting to open it with a filestream and a delay based retry mechanism. if you can't access the file because it's locked by another process, the code waits for a bit and then retries. If the file is opened and written by a completely different process it is rather hard to ensure a 100 % safe solution. the quickest way would be to let the writing process create a second file “isdone” alongside once it finished.
Asynchronous C Task Wait Method Called Not Finished Stack Overflow This example demonstrates how to wait until a file is completely written by attempting to open it with a filestream and a delay based retry mechanism. if you can't access the file because it's locked by another process, the code waits for a bit and then retries. If the file is opened and written by a completely different process it is rather hard to ensure a 100 % safe solution. the quickest way would be to let the writing process create a second file “isdone” alongside once it finished. There is no way to do this with the standard c library. the dupe does provide a good list of platform specific solutions. on linux , use inotify. no pure c or c way. you need to use an os api, such as posix for linux and windows api for windows. Simple answer is yes. the underlying stream is filled and closed (the important bit) before the writealltext method exits. file.writealltext method. creates a new file, write the contents to the file, and then closes the file. if the target file already exists, it is overwritten. There are a number of ways to do this, including a select loop. if you would rather block on a read until data is available, then do so on a single byte and fill in the remaining data afterward. How do i make ifstream wait until the file is completely written before parsing it? have whoever is writing the file deny read access while the file handle is open.
