## NAME

Pervasives.LargeFile - Operations on large files.

## Module

Module   Pervasives.LargeFile

## Documentation

Module **LargeFile**\
  :  **sig end**

Operations on large files. This sub-module provides 64-bit variants of the channel functions that manipulate file positions and file sizes.  By representing positions and sizes by 64-bit integers (type  **int64** ) instead of regular integers (type  **int** ), these alternate functions allow operating on files whose sizes are greater than  **max\_int** .
