New page

General/'''Memory''' is [[API]] for memory management.

== constant ==

== struct ==
typedef void* Memory;

== API ==
=== Memory Allocation===
#define MemoryAllocate(type,num,message) (type*)memoryAllocate(sizeof(type)*(num),message)

extern Memory memoryAllocate(size_t byte, char* message);

=== Release of memory ===
#define memoryFree(ptr) free(ptr)

=== Memory Copy as byte ===
Copy '''src''' to '''dst'''.
extern Memory memoryCopy(Memory dst, Memory src, size_t byte);

Allocate memory and Copy '''src''' to it.
extern Memory memoryDuplicate(Memory src, size_t byte);

===Memory Clear===
Data of '''src''' is overwritten at '''n'''.
extern Memory memoryClear(Memory src, size_t, char n);

===Byte swap===
Swap between 2 datas as byte. It is useful for converting Endian.
extern Memory memoryByteSwap(Memory src, size_t, int n);
Swap positions is different depending on '''size_t'''.
