cnfCalloc
- Allocate space that may be accessed from C and FORTRAN
- Description:
- This function allocates space in the same way as the standard C
calloc() 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 = cnfCalloc( nobj, size );
- Arguments:
-
-
size_t nobj (Given)
-
The number of objects for which space is required.
-
size_t size (Given)
-
The size of each object.
- Returned Value:
-
-
void *cnfCalloc
-
A registered pointer to the allocated space, or NULL if the
space could not be allocated.
- Notes:
- As with calloc(), the allocated space is initialised to zero
bytes.
- The space should be freed using
cnfFree
when no longer
required.
