int BM_Init(char *ockPath, int flags);

int BM_InitWithExtAttr(char *ockPath, int flags, void *attr);

int BM_Exit(void);

初始化

带属性的初始化

退出

int BM_CreateNSSec(const char *poolName, const char *ns, int attribute, const char *secId);

int BM_DestroyNSSec(const char *poolName, const char *ns, const char *secId);

int BM_QueryNSCache(QueryNsCache *buff, size_t buffLen);

Namespace创建和销毁、查询

int BM_AllocSec(BmInfo *bminfo, size_t size, int flags, BmAffinity* affinity);

int BM_FreeSec(BmInfo *bminfo, int flags);

int BM_BatchFreeSec(char *bmIdArray[], int num, int flags, const char *ns, const char *secId);

Bigmemory对象申请和释放

int BM_ExpandSec(BmInfo *bminfo, size_t size, int flags);

bigMemory扩容

int BM_MapSec(BmInfo *bminfo, int prot, int flags, void **ptr);

int BM_Unmap(char *bmId, void *ptr);

bigMemory到连续虚拟空间map和unmap

int BM_CopySec(BmInfo *srcBM, size_t srcOffset, BmInfo *dstBM, size_t dstOffset, size_t length, int flags);

bigMemory对象间拷贝

int BM_SpecificObjSwapInSec(DiskFileDesc *file, BmInfo *bminfo, int flags, size_t offset, size_t length);

文件内容换入bigmemory对象

int BM_ReadSec(BmInfo *bminfo, size_t offset, size_t length, void *buffer, int flags);

int BM_WriteSec(BmInfo *bminfo, size_t offset, size_t length, const void *buffer, int flags);

Bigmemory读写

int BM_GatherSec(intptr_t *inputInfo, BmOperatorCode operatorCode, int flags, BmInfo *bminfo, size_t *bmLen);
