Date: Mon, 25 Mar 2002 16:38:27 -0500 MIME-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 7bit X-Priority: 3 X-MSMail-Priority: Normal X-MimeOLE: Produced By Microsoft MimeOLE V5.50.4807.1700 Message-ID: X-OriginalArrivalTime: 25 Mar 2002 21:37:40.0726 (UTC) FILETIME=[4A49B160:01C1D445] Hi, Why does the screen output displayed using MSVC's printf subroutine not get shown immediately under Cygwin shell (bash, specifically)? Rather, it would wait for a long time before showing the text lines (many lines at once). How to change this behavior? I used the following (simple) code as an example: #include int main() { for (int i=0; i < 50; ++i) { printf("%d %d\n", i, i*i); for (int j=0; j < 10000000; ++j); /* just for delay */ } return 0; } Try to compile it using: gcc -mno-cygwin sample.c , then run it: ./a.exe. If you remove "-mno-cygwin", this strange behavior disappears. Under MS-DOS shell, this behavior does not exist.
