Casting a pointer from a char in C

Question

If I have a function that returns a (char) in c and I have a (char* getSomething) how do I cast it? It is giving me an error when I try to cast it through either (char*) or (char*)&

Example: If the function is :

char* getSomething;
getSomething = getSth(var);

getSth return a char

Answer 1

*getSomething = getSth(var);

Basically it says "put the char where getSomething points to..."
