我需要有关如何编写一个C程序的想法,该程序保留指定数量的MB RAM直到一个键[ex.在Linux 2.6 32位系统上按下任意键.
*
/.eat_ram.out 200
# If free -m is execute at this time, it should report 200 MB more in the used section, than before running the program.
[Any key is pressed]
# Now all the reserved RAM should be released and the program exits.
*
它是程序的核心功能[保留RAM]我不知道怎么做,从命令行获取参数,打印[按任意键]等等对我来说不是问题.
关于如何做到这一点的任何想法？
