NAME
Unix.LargeFile - File operations on large files.Module
Module Unix.LargeFileDocumentation
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
.
