Large File System Calls

A 32-bit program that supports large files that exceed two gigabytes in size must be able to process 64-bit file offsets. Because large files require use of large offsets, these files are manipulated through a parallel set of system interfaces. For more information, see the lf64(7) man page. These interfaces are documented in lf64, but they do not have individual man pages. Each of these large file system call interfaces appears as its own syscall probe as shown in the following table.
