I'm trying to use function fgets, but it always reads from standard input.
Here is the test code:
{ FILE *reg_file = fopen("1.txt", "r"); if (!reg_file) { perror(""); printf("Can't open file "%s"\n", "1.txt"); exit(1); } { char buf[100]; while (fgets(buf, 100, reg_file)) { printf("%s", buf); } exit(1); } }
The same code works correctly when compiled without Wine. One starange thing here that I do not see call to function fopen in the log. End of the log for the test application, called with --debugmsg +all, critical sections call are removed (note, the mail client wrapped the lines)

The bug, probably, is very simple and somebody can give me a clue basing on the trace.
I have fresh CVS Wine.
Thanks, Andriy Palamarchuk
