APPLICATION USAGE
The standard POSIX interfaces may be used by 32-bit applications to create and access large files if compiled with set to 64.
The interfaces described here are alternatives to the standard ones, and are enabled by defining
For 64-bit applications, access to large files is automatic, as long as the underlying file system is enabled for large files. The inter-
faces on this man page are available to 64-bit applications, for convenience in porting, but provide no additional capabilities. The
exception is which is not visible to 64-bit applications.
