<html><body style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; ">Hi All,<div><br></div><div>I'm now studying proc file system. I now know that read_proc_t function is called when the proofs file is read, and so for write_proc_t function when the proofs file is written to. But I also find the file_operaitons* field in the definition of proc_dir_entry, and this example code (<a href="http://linux.die.net/lkmpg/x810.html">http://linux.die.net/lkmpg/x810.html</a>). </div><div><br></div><div>So I'm confused that what happened if I provide both read_proc_t function, and the read function in file_operations structure? Thanks very much.</div><div><br></div><div>Best,</div><div>Siyuan</div></body></html>
