Hi, I could see getsubopt declaration in the unistd.h but in unix/linux its defined in stdlib.h i have also noticed that cygwin1.dll does not have that function implemented. as strings cygwin1.dll as of the 20060105 snapshot debug version did not give any results for the string getsubopt. Its well supported in all of the unices, i dont know how we missed on it. Thanks, Vijay
