C_LOC
— Obtain the C address of an objectC_LOC(X)
determines the C address of the argument.
Fortran 2003 and later
Inquiry function
RESULT = C_LOC(X)
X | Shall have either the POINTER or TARGET attribute. It shall not be a coindexed object. It shall either be a variable with interoperable type and kind type parameters, or be a scalar, nonpolymorphic variable with no length type parameters. |
The return value is of type C_PTR
and contains the C address
of the argument.
