cnfMalloc
- Allocate space that may be accessed from C and FORTRAN
- Description:
- This function allocates space in the same way as the standard C
malloc() function, except that the pointer to the space
allocated is automatically registered (using
cnfRegp)
for use
from both C and FORTRAN. This means that the returned pointer
may subsequently be converted into a FORTRAN pointer of type
F77_POINTER_TYPE (using
cnfFptr),
and back into a C pointer
(using
cnfCptr).
The contents of the space may therefore be
accessed from both languages.
- Invocation:
- cpointer = cnfMalloc( size );
- Arguments:
-
-
size_t size (Given)
-
The size of the required space.
- Returned Value:
-
-
void *cnfMalloc
-
A registered pointer to the allocated space, or NULL if the
space could not be allocated.
- Notes:
- The allocated space should be freed using
cnfFree
when no
longer required.
