upc_memset function
#include <upc.h>
void upc_memset(shared void *dst,
int c,
size_t n);
The upc_memset function copies the value of c, converted to an unsigned
char, to a shared object with affinity to any single thread. The number of
bytes set is n.
The upc_memset function treats the dst pointer as if had type:
shared [] char[n]
The effect is equivalent to setting the entire contents of a shared array object
with this type (the dst array) to the value c.
