Constants
- MODE_APPEND_READ_WRITE = 'a+b'
- Open for reading and writing; place the file pointer at the end of the file. If the file does not exist, attempt to create it.
- MODE_APPEND_WRITE = 'ab'
- Open for writing only; place the file pointer at the end of the file. If the file does not exist, attempt to create it.
- MODE_CREATE_READ_WRITE = 'x+b'
- Create and open for reading and writing; place the file pointer at the beginning of the file. If the file already exists, the fopen() call with fail by returning false and generating an error of level E_WARNING. If the file does not exist, attempt to create it. This is equivalent to specifying O_EXCL | O_CREAT flags for the underlying open(2) system call.
- MODE_CREATE_WRITE = 'xb'
- Create and open for writing only; place the file pointer at the beginning of the file. If the file already exits, the fopen() call with fail by returning false and generating an error of level E_WARNING. If the file does not exist, attempt to create it. This is equivalent to specifying O_EXCL | O_CREAT flags for the underlying open(2) system call.
- MODE_READ = 'rb'
- Open for reading only; place the file pointer at the beginning of the file.
- MODE_READ_WRITE = 'r+b'
- Open for reading and writing; place the file pointer at the beginning of the file.
- MODE_TRUNCATE_READ_WRITE = 'w+b'
- Open for reading and writing; place the file pointer at the beginning of the file and truncate the file to zero length. If the file does not exist, attempt to create it.
- MODE_TRUNCATE_WRITE = 'wb'
- Open for writing only; place the file pointer at the beginning of the file and truncate the file to zero length. If the file does not exist, attempt to create it.
