Class

Inquiry function

Syntax

Return value

The return value is of type c_funptr and contains the C address of the argument.

Example

module x
 use iso_c_binding
 implicit none
contains
 subroutine sub(a) bind(c)
 real(c_float) :: a
 a = sqrt(a)+5.0
 end subroutine sub
end module x
program main
 use iso_c_binding
 use x
 implicit none
 interface
 subroutine my_routine(p) bind(c,name='myC_func')
 import :: c_funptr
 type(c_funptr), intent(in) :: p
 end subroutine
 end interface
 call my_routine(c_funloc(sub))
