cnfCref
- Create a temporary FORTRAN CHARACTER string and return a pointer to it.
- Description:
- Memory is obtained for a FORTRAN CHARACTER string of the specified
length and a pointer is returned which may be passed from C to a FORTRAN
subroutine. The string is not initialised to blanks.
- Invocation:
- string_f = cnfCref( string_f_len )
- Arguments:
-
-
int string_f_len (Given)
-
The required length of the FORTRAN string.
- Returned Value:
-
-
F77_CHARACTER_ARG_TYPE *cnfCref
-
A pointer to the storage that has been allocated by this routine.
Note that this is not necessarily the location of the string of
characters.
- Notes:
- If the routine could not create the space, then it returns a
null pointer.
- This function will usually be called via the F77
F77_CREATE_CHARACTER macro which will also provide a
pointer to the actual string of characters.
