@chapter Large File Input and Output (@file{stdio.h})
|
|
|
|
This chapter comprises additional functions to manage large files which
|
|
are potentially larger than 2GB.
|
|
|
|
The underlying facilities for input and output depend on the host
|
|
system, but these functions provide a uniform interface.
|
|
|
|
The corresponding declarations are in @file{stdio.h}.
