SYNOPSIS
DESCRIPTION
New API's to support large files in 32-bit applications. These API interfaces are not a part of the POSIX standard and may be removed in the future. The function returns a file descriptor which can be used to grow the file past 2 GB if desired. All other functional behaviors, returns, and errors are identical to The function is identical to except that returns file status in a instead of a All other functional behaviors, returns, and errors are identical. The function is indentical to except that returns file status in a struct instead of a struct The function is identical to except that passes a as its second parameter instead of a All other functional behaviors, returns, and errors are identical. The function is identical to except that accepts an for the size parameter instead of All other functional behaviors, returns, and errors are identical. The function is identical to except that accepts an type as the desired offset and has a return value of All other functional behaviors, returns, and errors are identical. The function is identical to except that returns file status in a instead of All other functional behaviors, returns, and errors are identical. The function is identical to except that accepts the file offset as an The function opens files of any size. It returns a file descriptor which can be used to grow the file past 2 GB if desired.

This bit is automatically set by and if is set to 64. The bit may be queried by (or which can also turn the bit on or off if desired.
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 interfaces 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 applica- tions.
