Re^2: Detect whether a writeable filehandle has closed?

Maybe an END block in the child could signal that the filehandle is gone

The child is not perl, it's a compiled C program.

OK, so perhaps using the `_atexit` call (or whatever the equivalent is in your RTL) in the C code. The general idea is for the code to catch that the child has exitted and signal the caller. Alex / talexb / Toronto Thanks PJ. We owe you so much. Groklaw -- RIP -- 2003 to 2013.	[reply] [d/l]
