Note: This package is deprecated. It is highly preferred that instead of using this code base that instead or is used instead. For any questions or comments or further help needed please email and prefix your email subject with oslopylockfile (for a faster response). The lockfile package exports a LockFile class which provides a simple API for locking files. Unlike the Windows msvcrt.locking function, the fcntl.lockf and flock functions, and the deprecated posixfile module, the API is identical across both Unix (including Linux and Mac) and Windows platforms. The lock mechanism relies on the atomic nature of the link (on Unix) and mkdir (on Windows) system calls.

Original doom for pc free download. An implementation based on SQLite is also provided, more as a demonstration of the possibilities it provides than as production-quality code. Note: In version 0.9 the API changed in two significant ways:. It changed from a module defining several classes to a package containing several modules, each defining a single class. Where classes had been named SomethingFileLock before the last two words have been reversed, so that class is now SomethingLockFile. The previous module-level definitions of LinkFileLock, MkdirFileLock and SQLiteFileLock will be retained until the 1.0 release.

Hello everyone, I have searched for this high and low but could not find a solution. To elaborate on the heading. I am trying to figure out a way to do this: 1. I have a text file with one line paths and file listing in it, for example: E: Movies 1408.avi E: Movies 28.Days.Later2002 E: Movies 88Minutes-Gr8 Movie E: Movies Airplane.Part1!1980 2. I would like to show one line at a time to the user on a command based program (windows cmd) and let them 'EDIT' the 'pre-loaded' text and press enter (accept it in a variable as string). Again as an example, I want the output to be something like this: # Step 1 (Output) The movie: E: Movies 28.Days.Later2002 #.
'Utilities to get a password and/or the current user name. Getpass(prompt, stream) - Prompt for a password, with echo turned off.
Getuser - Get the user name from the environment or password database. GetPassWarning - This UserWarning is issued when getpass cannot prevent echoing of the password contents while reading. On Windows, the msvcrt module will be used.

– Useful routines from the MS VC runtime These functions provide access to some useful capabilities on Windows platforms. Some higher-level modules use these functions to build the Windows implementations of their services. For example, the module uses this in the implementation of the function. Further documentation on these functions can be found in the Platform API documentation. The module implements both the normal and wide char variants of the console I/O api. The normal API deals only with ASCII characters and is of limited use for internationalized applications.
The wide char API should be used where ever possible. File Operations msvcrt. Locking ( fd, mode, nbytes ) Lock part of a file based on file descriptor fd from the C runtime. Raises on failure. The locked region of the file extends from the current file position for nbytes bytes, and may continue beyond the end of the file. Mode must be one of the LK. constants listed below.
Multiple regions in a file may be locked at the same time, but may not overlap. Adjacent regions are not merged; they must be unlocked individually. LKLOCK msvcrt.
LKRLCK Locks the specified bytes. If the bytes cannot be locked, the program immediately tries again after 1 second. If, after 10 attempts, the bytes cannot be locked, is raised. LKNBLCK msvcrt. LKNBRLCK Locks the specified bytes. If the bytes cannot be locked, is raised. LKUNLCK Unlocks the specified bytes, which must have been previously locked.
Setmode ( fd, flags ) Set the line-end translation mode for the file descriptor fd. To set it to text mode, flags should be; for binary, it should be. Openosfhandle ( handle, flags ) Create a C runtime file descriptor from the file handle handle. The flags parameter should be a bitwise OR of,. The returned file descriptor may be used as a parameter to to create a file object. Getosfhandle ( fd ) Return the file handle for the file descriptor fd.
Raises if fd is not recognized. Console I/O msvcrt. Kbhit ( ) Return true if a keypress is waiting to be read. Getch ( ) Read a keypress and return the resulting character. Nothing is echoed to the console. This call will block if a keypress is not already available, but will not wait for Enter to be pressed.
If the pressed key was a special function key, this will return ' 000' or ' xe0'; the next call will return the keycode. The Control-C keypress cannot be read with this function. Getwch ( ) Wide char variant of, returning a Unicode value. New in version 2.6. Getche ( ) Similar to, but the keypress will be echoed if it represents a printable character. Getwche ( ) Wide char variant of, returning a Unicode value.
New in version 2.6. Putch ( char ) Print the character char to the console without buffering.
Putwch ( unicodechar ) Wide char variant of, accepting a Unicode value. New in version 2.6. Ungetch ( char ) Cause the character char to be “pushed back” into the console buffer; it will be the next character read. Ungetwch ( unicodechar ) Wide char variant of, accepting a Unicode value. New in version 2.6.
