Hi ,

These are plain C question, that is why I asked them here.

These are not due to not  including header files.
the gcc that comes with CYGWIN cabot find the proper libraries.

That is y I asked this question.

I thought somebody here might know what library will have thse functions in 
CYGWIN.

Can u help me here

Vikram
