object Stdio.sendfile(array(string) headers, File from, int offset, int len, array(string) trailers, File to)
object Stdio.sendfile(array(string) headers, File from, int offset, int len, array(string) trailers, File to, function(int:void) callback, mixed ... args)
- Description
-
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
-
The sending is performed asynchronously, and may complete
before or after the function returns.
For callback to be called, the backend must be active (ie
main() must have returned -1 , or Pike.DefaultBackend
get called in some other way).
In some cases, the backend must also be active for any sending to
be performed at all.
