Class _Stdio.sendfile

Description

Send headers + from_fd[off..off+len-1] + trailers to to_fd asyncronously.

Note

This is the low-level implementation, which has several limitations. You probably want to use Stdio.sendfile() instead.

Method create

_Stdio.sendfile _Stdio.sendfile(array(string) headers, object from, int offset, int len, array(string) trailers, object to, function(:void) callback, mixed ... args)

Description

Low-level implementation of Stdio.sendfile().

Sends headers followed by len bytes starting at offset from the file from followed by trailers to the file to. When completed callback will be called with the total number of bytes sent as the first argument, followed by args.

Any of headers, from and trailers may be left out by setting them to 0.

Setting offset to -1 means send from the current position in from.

Setting len to -1 means send until from's end of file is reached.

Note

Don't use this class directly! Use Stdio.sendfile() instead.

In Pike 7.7 and later the callback function will be called from the backend associated with to.

Note

May use blocking I/O and thus trigger process being killed with SIGPIPE when the other end closes the connection. Add a call to signal() to avoid this.
