在复制C号插图时,我必须注意哪些因素? 什么是错的?
我认为,在复制插图之前,我需要保留足够的记忆,并且必须保证我有足够的特权来书写记忆(避开一般保护ault),但是,在复制插图时,我还必须注意什么? 是否有其他潜在的错误?
0 = ).Cstrings是非零用 by体的常规阵列,最后是零件。 与他们打交道的例行公事可以到一旁(从那边起就进入阵列)。 你们应当注意保留地的位置。 学习strcpy和strcat及其约束的对应部分strncpy和strncat。 另见<代码>strdup。 不要忘记将逐字确定为零(特别是在达到<条码>载荷/代码>等的约束时)。 一些图书馆(例如德国技术合作公司Glib)提供冰电功能(例如:g_strdup_printf)
Read the documentation of all the functions I mentioned.
