140 * \def fsw_alloc(size,ptrptr)
141 * Allocate memory on the heap. This function or macro allocates \a size
142 * bytes of memory using host-specific methods. The address of the
143 * allocated memory block is stored into the pointer variable pointed
144 * to by \a ptrptr. A status code is returned; FSW_SUCCESS if the block
145 * was allocated or FSW_OUT_OF_MEMORY if there is not enough memory
146 * to allocated the requested block.
151 * Release allocated memory. This function or macro returns an allocated
152 * memory block to the heap for reuse. Does not return a status.
156 * \def fsw_memcpy(dest,src,size)
157 * Copies a block of memory from \a src to \a dest. The two memory blocks
158 * must not overlap, or the result of the operation will be undefined.
159 * Does not return a status.
163 * \def fsw_memeq(dest,src,size)
164 * Compares two blocks of memory for equality. Returns boolean true if the
165 * memory blocks are equal, boolean false if they are different.
169 * \def fsw_memzero(dest,size)
170 * Initializes a block of memory with zeros. Does not return a status.
