Any help on this would be appreciated:
| I have a parent and a child (thru forking) that needs to talk to each
| other thru a
| socket pair pipe. Communication works fine, but the problem happens
when
| I try
| to read from a pipe that has no data in it. The read, which is like
| $readline = <CHILD> ;
| keeps waiting till the child has some data in it. I know that this is
| how it is supposed
| to work, but is there any way I could check whether there is some
data
| in the pipe
| before I read the pipe ?
|
| Thanx
| Amar
