4.1. CONVENIENCE ALLOCATION PROGRAMS (ALLOC.C) 41
Output
ptr
a void pointer pointing to the allocated block of memory.
4.1.14 sf boolalloc2
Allocates a 2D array in the memory for the bool type. It works just like sf boolalloc
but does it for two dimensions. This is done by making a pointer point to another pointer,
which in turn points to a particular column (or row) of an allocated 2D block of memory
of size n1*n2. n1 is the fastest dimension.
Call
ptr = sf_boolalloc2 (n1, n2);
Definition
bool **sf_boolalloc2 (size_t n1 /* fast dimension */,
size_t n2 /* slow dimension */)
/*< bool 2-D allocation, out[0] points to a contiguous array >*/
{
...
}
Input parameters
n1
n2
number of elements in the fastest dimension (size t).
number of elements in the slower dimension (size t).
Output
ptr
a void pointer pointing to the allocated block of memory.
4.1.15 sf boolalloc3
Allocates a 3D array in the memory for the bool type. It works just like sf boolalloc2
but does it for three dimensions. This is done by extending the same argument as for
