Large File System Calls

A 32-bit program that supports large files that exceed four gigabytes in size must be able to process 64–bit file offsets. Because large files require use of large offsets, large files are manipulated through a parallel set of system interfaces, as described in lf64(5). 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 Table 21–1.
