But I got [hjl@gnu-6 tmp]$ cat s.c #include <stdio.h> int main() { int count; float quant; char buf[100]; count = fscanf(stdin, "%f%s", &quant, buf); printf ("quant = %lf\n",quant ); printf ("count = %d\n", count); printf ("string = %s\n", buf); return 0; } [hjl@gnu-6 tmp]$ gcc s.c [hjl@gnu-6 tmp]$ cat x.input 100ergs of energy [hjl@gnu-6 tmp]$ ./a.out < x.input quant = 100.000000 count = 2 string = rgs [hjl@gnu-6 tmp]$ I was told that Windows and MacOS behave the same as glibc. -- Configure bugmail: http://sourceware.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
