In Linux 2.4 and earlier, out_fd could also refer to a regular file; this possibility went away in the Linux 2.6.x kernel series, but was restored in Linux 2.6.33. The original Linux sendfile() system call was not designed to handle large file offsets.

The sendfile(2) function requires support from both the Unix kernel and from the filesystem drivers which handle the filesystems for the file descriptors being used. The following operating systems have had reports of issues when using sendfile(2): AIX 5.2; Solaris 10 x86; PA-RISC Linux

1. A kernel with sendfile support (i.e. 2.4.X) 2. A network card capable of doing the TCP checksum in the hardware 3. The application must support sendfile Do you know what applications support zerocopy (sendfile)? I noticed that a zerocopy NFS patch was added to the 2.5.x tree. Does the 2.4.X NFS daemon support zerocopy?

Question: Tag: android,splice,sendfile Does Android support splice() and sendfile()? Answer: These are Linux kernel calls, so they do exist on Android. The more interesting question is if Bionic libc provides wrappers as it does for most ordinarily used system calls, or if you will have to invoke them directly.

NAME sendfile - transfer data between file descriptors SYNOPSIS #include <sys/sendfile.h> ssize_t sendfile(int out_fd, int in_fd, off_t *offset, size_t count); DESCRIPTION sendfile() copies data between one file descriptor and another.Because this copying is done within the kernel, sendfile() is more efficient than the combination of read(2) and write(2), which would require …

Apache recommend against using sendfile() with Linux NFS because their software is popular and triggered many painful to debug sendfile related bugs with older Linux NFS clients. The warning is old and it's probably easier to leave it as-is rather than update it with all the caveats.
http://man7.org/linux/man-pages/man2/sendfile.2.html
The in_fd argument must correspond to a file which supports mmap(2) -like operations (i.e., it cannot be a socket). In Linux kernels before 2.6.33, out_fd must refer to a socket. Since Linux 2.6.33 it can be any file. If it is a regular file, then sendfile () changes the file offset appropriately.

sendfile is Linux-specific. It tells the kernel to do zero-copy I/O from a file to a socket. It tells the kernel to do zero-copy I/O from a file to a socket. (Note that it only works when the source fd is a file and the destination is a socket; for generic Linux-specific zero-copy I/O, read about splice() .)
