Memory allocation macros [macros]

Memory allocation macros

These macros allow slightly simplified handling of memory.

• sgs_Malloc( C, size ): allocates the memory (alias to sgs_Memory( C, NULL, size )).
• sgs_Free( C, ptr ): frees the memory (alias to sgs_Memory( C, ptr, 0 )).
• sgs_Realloc: alias to sgs_Memory.
• The following macros expect that the variable sgs_Context* C is in the scope:
  • sgs_Alloc( what ): allocates enough memory to fit the specified type what;
  • sgs_Alloc_n( what, n ): allocates enough memory to fit n instances of the specified type what;
  • sgs_Alloc_a( what, app ): allocates enough memory to fit the specified type what and app more bytes;
  • sgs_Dealloc( ptr ): frees the memory.
• All of these functions, including sgs_Memory, work on the same heap, thus they are interchangeable.
