A portable persistent memory allocation library.

Features:

• Optimized memory layout arrangement
• persistent key-value pair storage (fixed length)
• portable address support
• in-place structured data persistence

How to use it ?

setup a memory descriptor for persistent memory pool

/* attache to a file hander */void*md=pmalloc_attach(fd, NULL, PM_CAPACITY);
/* capture error */assert(NULL!=md);
....
/* close it */pmalloc_detach(md);

manipulate persistent memory blocks

for (i=0; i<16; ++i)
{
/* fetch persistent key values */key=pmalloc_getkey(md, i);
if (NULL!=key)
printf("Prekey... %p --> %s %lu\n", key, (char*)key, sizeof(size_t));
elsebreak;
}
...
/* allocate a memory block with specified size */void*data=pmalloc(md, 0x1000*5);
if (NULL!=data) {
sprintf(data, "output data row %d", i);
/* put it on key-value pair store */pmalloc_setkey(md, i, data);
}
...
/* retrieve a persisted memory block from key-value pair store with a specified key */keydata=pmalloc_getkey(md, keyidx);
if (NULL!=keydata) {
/*freeupanallocatedblockpmfree(md, keydata);
pmalloc_setkey(md, keyidx, NULL);
printf(ANSI_COLOR_GREEN"Released original key data at %p! \n"ANSI_COLOR_RESET, keydata);
} elseprintf(ANSI_COLOR_CYAN"No original key data set in this key slot! \n"ANSI_COLOR_RESET);
