Field Documentation

Alloc

void *(* CMUTIL_Mem::Alloc) (size_t size)

Allocate memory.

Allocates size bytes and returns a pointer to the allocated memory. The memory is not initialized. If size is 0, then this function returns either NULL or a unique pointer value that can later be successfully passed to Free.

Parameters

size	Count of bytes to be allocated.

Returns

A pointer to the allocated memory, which is suitably aligned for any built-in type. On error this function returns NULL. NULL may also be returned by a successful call to this function with a size of zero.

Calloc

void *(* CMUTIL_Mem::Calloc) (size_t nmem, size_t size)

Allocate memory with zero filled.

Parameters

nmem	Count of memory elements to be allocated.
size	Size of each memory element.

Returns

A pointer to the allocated memory, which is suitably aligned for any built-in type. On error this function returns NULL. NULL may also be returned by a successful call to this function with a size of zero.

Realloc

void *(* CMUTIL_Mem::Realloc) (void *ptr, size_t size)

Reallocate memory.

Parameters

ptr	Pointer to the memory block to be reallocated.
size	New size of the memory block.

Returns

A pointer to the reallocated memory, which is suitably aligned for any built-in type. On error this function returns NULL. NULL may also be returned by a successful call to this function with a size of zero.

Strdup

char *(* CMUTIL_Mem::Strdup) (const char *str)

Duplicate a string.

Parameters

str	Pointer to the string to be duplicated.

Returns

A pointer to the duplicated string, which is suitably aligned for any built-in type. On error this function returns NULL. NULL may also be returned by a successful call to this function with a str of NULL.

Free

void(* CMUTIL_Mem::Free) (void *ptr)

Free memory.

Parameters

ptr	Pointer to the memory block to be freed.
