Detailed Description
The functions in this file help with using low-level Unix-style file descriptors, BSD sockets and directories. In general, they retain the prototype and most semantics from their respective standard equivalents. However, there are a few differences:
- On Windows, file path arguments are expected in UTF-8 format. They are converted to UTF-16 internally, thus enabling access to paths outside of the local Windows ANSI code page.
- On POSIX systems, file descriptors are created with the close-on-exec flag set (atomically where possible), so that they do not leak to child process after fork-and-exec.
- vlc_scandir(), inspired by GNU scandir(), passes file names rather than dirent structure pointers to its callbacks.
- vlc_accept() takes an extra boolean for nonblocking mode (compare with the flags parameter in POSIX.next accept4()).
- Writing functions do not emit a SIGPIPE signal in case of broken pipe.
