MLCheckFunction()

int MLCheckFunction(MLINK link, char *name, long *n) checks that a function whose head is a symbol with the specified name is on link, and stores the number of the arguments of the function in n.

MLCheckFunction() returns 0 if the current object on the link is not a function with a symbol as a head, or if the name of the symbol does not match name.
