linux-toradex.git/tools/include/nolibc/sys/sendfile.h, branch master Linux kernel for Apalis and Colibri modules tools/nolibc: Add sendfile() 2026-08-31T04:19:24+00:00 Daniel Palmer daniel@thingy.jp 2026-08-28T10:32:04+00:00 c0da8b53603ad84f622b2c5f6c1a69f7d4b4b8bc This is useful because it allows copying data up to 2GB from one fd to another without a buffer in userspace and with a single syscall. For 32bit kernels we use the sendfile64 syscall to allow for 64bit offsets to work.
