 | | Although the title of this chapter might indicate that the functions just discussed are not used very often, this is only partially true. In particular, the select and poll functions are used frequently in programs that must manage multiple data streams; many network-based programs fall into this category. The fcntl function is also used fairly often, although only some of its options are used routinely. And finally, file and record locking is used with some regularity. | |
