Hi,
I don't find the way to check if the input I give to the function scanf is
an int or a char. For example you ask to enter an int, and if a char is
entered -> BUG, so I need something to check if tne input is an int.
It's easy to check if it's a char, but int .... I didn't find.

I wrote this function but it doesnt work, can you help me .....

int input_one_int(char CHAINEval[],int MAXval,int MINval)// Rmq: Bug if char
entered
{

int test=0,check=0,value;

do
   {
    printf("\r%s : ",CHAINEval);
    fflush(stdout);
    fflush(stdin);
    test=scanf("%d*[^\n]",&value);
    if (test==EOF)
       {
       printf("syntax error");
       }
    if ((value<=MAXval)&&(value>=MINval)) check=1;
    } while ((test!=1)||(check==0));

return value;




thank for any help ...
