e. The user is responsible for making sure this memory
location is of the appropiate size/type (see the returned types below to
determine the size/type). The function returns
TRUE on
success and FALSE on failure.
PL_ATOM- Retrieve a flag whose value is an
atom. The returned value is an atom handle of typeatom_t. PL_INTEGER- Retrieve a flag whose value is an
integer. The returned value is an integer of typeint64_t. PL_FLOAT- Retrieve a flag whose value is a
float. The returned value is a floating point number of typedouble. PL_TERM- Retrieve a flag whose value is a
term. The returned value is a term handle of typeterm_t.
