MUMPS_ADDR_C()

void MUMPS_CALL MUMPS_ADDR_C	(	char *	a,
		MUMPS_INT8 *	addr )

Definition at line 22 of file mumps_size.c.

{
*addr=*(MUMPS_INT8*)&a;
/*
    With the form "*addr=(MUMPS_INT8)a", "(MUMPS_INT8)a"
    and "a" may have different binary representations
    for large addresses. In the above code, "(MUMPS_INT8*)&a"
    is a pointer to the address "a", considering that "a" is
    a MUMPS_INT8 rather than an address. Then the content of
    that pointer is the exact binary representation of the
    address a, but stored in a MUMPS_INT8 (signed 64-bit
    integer).
