NAME¶
do_splice_direct - splices data directly between two files
SYNOPSIS¶
long do_splice_direct(struct file * in, loff_t * ppos, struct file * out, loff_t * opos, size_t len, unsigned int flags);
ARGUMENTS¶
in
file to splice from
ppos
input file offset
out
file to splice to
opos
output file offset
len
number of bytes to splice
flags
splice modifier flags
DESCRIPTION¶
For use by do_sendfile. splice can easily emulate sendfile, but doing it in the application would incur an extra system call (splice in + splice out, as compared to just sendfile). So this helper can splice directly through a process-private pipe.
