I'm not sure if this is legal. In any case, here is a reduced test case:
module m_odbc_if
implicit none
interface sql_set_env_attr
function sql_set_env_attr_int( input_handle,attribute,value,length ) &
result(res) bind(C,name="SQLSetEnvAttr")
use, intrinsic :: iso_c_binding
implicit none
type(c_ptr), value :: input_handle
integer(c_int), value :: attribute
integer(c_int), value :: value
integer(c_int), value :: length
integer(c_short) :: res
end function
function sql_set_env_attr_ptr( input_handle,attribute,value,length ) &
result(res) bind(C,name="SQLSetEnvAttr")
use, intrinsic :: iso_c_binding
implicit none
type(c_ptr), value :: input_handle
integer(c_int), value :: attribute
type(c_ptr), value :: value
integer(c_int), value :: length
integer(c_short) :: res
end function
end interface
end module
