|
||||
specified with the name "FILE.mpeg" is interpreted as the URL
|
||||
"file:FILE.mpeg".
|
||||
|
||||
This protocol accepts the following options:
|
||||
|
||||
@table @option
|
||||
@item truncate
|
||||
Truncate existing files on write, if set to 1. A value of 0 prevents
|
||||
truncating. Default value is 1.
|
||||
|
||||
@item blocksize
|
||||
Set I/O operation maximum block size, in bytes. Default value is
|
||||
@code{INT_MAX}, which results in not limiting the requested block size.
|
||||
Setting this value reasonably low improves user termination request reaction
|
||||
time, which is valuable for files on slow medium.
