CHARACTER_ARRAY_ARG
- Pass a CHARACTER array argument to a FORTRAN routine
- Description:
- Pass a CHARACTER array argument to a FORTRAN routine. The
argument should be the address of a CHARACTER array.
- Invocation:
- CHARACTER_ARRAY_ARG(p_arg)
- Arguments:
-
-
p_arg
-
A pointer to the actual array being passed.
- Examples:
-
- CHARACTER_ARRAY_ARG(charg)
- will expand as follows:
All Unix: |
(char *)charg |
VAX/VMS: |
charg_arg |
- Notes:
- The cast in the expansion for Unix ensures that multi-dimensional
arrays (arrays of arrays), for example as declared by
DECLARE_type_ARRAY, may be passed.
