Function Documentation

sfree()

void sfree

(

void *

p

)

Free the memory block pointed to by the specified pointer.

Parameters

p	The pointer to the memory block to free.

smalloc()

void * smalloc

(

uint32_t

num_bytes

)

Allocate a block of memory from the heap with the specified size.

Parameters

num_bytes

The number of bytes to allocate.

Returns

A pointer to the allocated memory block, or NULL if allocation fails.

smalloc_init()

int32_t smalloc_init	(	uint32_t	p_heap_head,
		uint32_t	n_heap_size
	)

Initialize the simple malloc library with the specified heap parameters.

Parameters

p_heap_head	The starting address of the heap.
n_heap_size	The size of the heap in bytes.

Returns

Zero if successful, non-zero otherwise.

srealloc()

void * srealloc	(	void *	p,
		uint32_t	num_bytes
	)

Reallocate a block of memory with the specified new size.

Parameters

p	The pointer to the memory block to reallocate.
num_bytes	The new size in bytes.

Returns

A pointer to the reallocated memory block, or NULL if reallocation fails.
