Is it possible to change the size of a named pipe on Linux?
I know that for the current version of the Linux kernel, the size of named pipes is 64K. Is it possible to increase this size at all?
I know I can switch to sockets, but first I'd like to see if I can solve an intermittent 开发者_如何学JAVAbuffer-overflow problem by just increasing the named-pipe size.
With recent kernels (>= 2.6.35), you can change the size of a pipe with
fcntl(fd, F_SETPIPE_SZ, size)
where size
is a long
. The maximum size is in /proc/sys/fs/pipe-max-size
.
