Shm_unlink(): Deletes a shared memory region given a file descriptor ( returned from shm_open()). shmunlink():根据(shmopen()返回的)文件描述符,删除共享内存段。
A reference was made to a segment not present in memory ( one in which the Segment-Present flag of the Segment Descriptor was cleared). 引用一个不在内存中的段(段描述符的段存在标志为空)。
Unable to allocate enough local memory for share security descriptor. 无法给共享安全描述符分配足够的本地内存。
This paper proposed a share-memory switch structure which is adopted into GPON system, and a memory management method based on packet descriptor. 本文主要研究共享缓存交换结构在GPON系统中的应用,并设计了一种基于数据包描述符的缓存管理方式。
