The MulDiv convenience function in Windows API is equivalent to (a*b)/c, but it stores the intermediate result of a*b in a 64-bit variable before dividing it by c to avoid integer overflow where a*b is greater than MAX_INT but (a*b)/c is not.

WINAPI
MulDiv(
_In_ int nNumber,
_In_ int nNumerator,
_In_ int nDenominator
);
When programming in Linux, is there an equivalent convenience function?

It seems there is no equivalent function for Linux.
I created a simple inline function that works (I haven't tested it with 64-bit compilation though)
inline int mul_div(int number, int numerator, int denominator) {
long long ret = number;
ret *= numerator;
ret /= denominator;
return (int) ret;
}
