void*malloc(size_tsize); Here,sizerepresents the number of bytes to allocate. The function returns a pointer of typevoid*which can be cast to any desired data type. Return Type and Parameter The return value ofmalloc()is quite significant. If the function successfully allocates the desired ...
One common use ofvoid pointersis in memory allocation functions such asmalloc()which returns a void pointer point to a block of memory that can be used to store any data type. The programmer can then cast the void pointer to the appropriate data type to access and manipulate the data store...

1. What are the basic data structures in C, and how are they used? The basic data structures in C include arrays, stacks, queues, linked lists, trees, and graphs. Arrays store elements of the same type in contiguous memory, enabling fast indexing. Stacks use a last-in, first-out (LIF...
The type is stored in type as a bit-flag (this means that you cannot find out the type by just comparing the value of type). To check the type of an item, use the corresponding cJSON_Is... function. It does a NULL check followed by a type check and returns a boolean value if ...
rocBLAS functions run on the host, and they call HIP to launch rocBLAS kernels that run on the device in a HIP stream. The kernels are asynchronous unless: The function returns a scalar result from device to host Temporary device memory is allocated In both cases above, the launch can be ...
