C Question

Function to get minimum of three or more arguments in C

In the library in C/C++, the function fmin(x,y) returns the minimum value of the two arguments x and y, as documented for instance in the C++ reference.

However, is there a similar function fminimum(a,b,c,...x,y,z) available that finds the minimum of three or more arguments of the same data type?

EDIT: sorry for the confusion. This question is restricted only to C, so no C++

The old fashioned way...

int arr[] = { 1, 3, 6, 100, 50, 72 };

int min_array( int arr[], int len )
    int min = arr[0];

    for ( int i = 1; i < len; i++ )
        if ( arr[i] < min )
            min = arr[i];

    return min;
