We are working on PPC target and using QNX 6.3.0 SP1 .
We are mounting fs-cifs file system on  a PC in the same network.
On the PC  one file is created and data is written using fwrite() to that file form the hadrware.
fwrite()  is used in a loop.
If network cable is unplugged from the PC then fwrite() is getting blocked until the cable is reconnected.
Why fwrite() is getting blocked?
is there any solution to avoid the block on fwrite()??
