Detailed Description

Header for a simple implementation of malloc().

Todo:
: This library may currently be broken.

Macro Definition Documentation

◆ MALLOC_FREE

#define MALLOC_FREE   1

The malloc hunk flags Note: Cound have used a negative size a'la TI

◆ MALLOC_USED

#define MALLOC_USED   2

◆ MALLOC_MAGIC

#define MALLOC_MAGIC   123

Magic number of a header. Gives us some chance of surviving if the list is corrupted

Typedef Documentation

typedef struct smalloc_hunk mmalloc_hunk

◆ pmmalloc_hunk

typedef struct smalloc_hunk* pmmalloc_hunk

Function Documentation

◆ malloc_gc()

void malloc_gc ( void  )

Garbage collect (join free hunks)

◆ debug()

void debug ( char *  routine,
char *  msg 
)

debug message logger

Variable Documentation

◆ malloc_heap_start

UBYTE malloc_heap_start
extern

Start of free memory, as defined by the linker

◆ malloc_first

pmmalloc_hunk malloc_first
