module LargeFile: sig end
File operations on large files.
This sub-module provides 64-bit variants of the functions
Unix.lseek (for positioning a file descriptor),
Unix.truncate and
Unix.ftruncate (for changing the size of a file),
and
Unix.stat,
Unix.lstat and
Unix.fstat (for obtaining
information on files). These alternate functions represent
positions and sizes by 64-bit integers (type
int64) instead of
regular integers (type
int), thus allowing operating on files
whose sizes are greater than
max_int.
