io_block(3) Library Functions Manual io_block(3)NAME
io_block - switch to blocking I/O
SYNTAX
#include <io.h>
void io_block(int64 fd);
DESCRIPTION
io_block puts UNIX descriptor fd into ``blocking mode.''
File descriptors are normally in blocking mode, except if they come from accept() or io_accept() and the listening socket was in non-block-
ing mode.

io_tryread(3) Library Functions Manual io_tryread(3)NAME
io_tryread - read from a descriptor without blocking
SYNTAX
#include <io.h>
int io_tryread(int64 fd,char* buf,int64 len);
DESCRIPTION
io_tryread tries to read len bytes of data from descriptor fd into buf[0], buf[1], ..., buf[len-1]. (The effects are undefined if len is 0
or smaller.) There are several possible results:
o o_tryread returns an integer between 1 and len: This number of bytes was available for immediate reading; the bytes were read into the
beginning of buf. Note that this number can be, and often is, smaller than len; you must not assume that io_tryread always succeeds in
reading exactly len bytes.
o io_tryread returns 0: No bytes were read, because the descriptor is at end of file. For example, this descriptor has reached the end of
a disk file, or is reading an empty pipe that has been closed by all writers.
o io_tryread returns -1, setting errno to EAGAIN: No bytes were read, because the descriptor is not ready. For example, the descriptor is
reading an empty pipe that could still be written to.
o io_tryread returns -3, setting errno to something other than EAGAIN: No bytes were read, because the read attempt encountered a persis-
tent error, such as a serious disk failure (EIO), an unreachable network (ENETUNREACH), or an invalid descriptor number (EBADF).
io_tryread does not pause waiting for a descriptor that is not ready. If you want to pause, use io_waitread or io_wait.
You can make io_tryread faster and more efficient by making the socket non-blocking with io_nonblock().

Hi there,
I'm puzzled. Compressing the same file (same name, same md5sum) at two different times will produce a different output. I mean the md5sum of the resulting .gz files are different.
Does it make any sens to any of you?
I'd like some explanations if you know what's going on.
Thanks... (4 Replies)

How do I find the files greater than or equal to a given size using find command.
find ./ -size +0k --> Lists files greater than 0K
find ./ -size 0k --> Lists the file size equal to 0K.
I have other conditions to check, hence using find command.
Thanks in advance. (4 Replies)
