windows向linux移植中可能会遇到的个问题.docxVIP

1.斜杠的调查 在路径中斜杠/和反斜杠/的使用,在WIN下,系统和编译器都能识别正反斜杠,所以怎么用都无所谓;但是在LINUX下,只能识别斜杠/,所以在写代码时,路径分隔符请不要使用反斜杠/,而都应当用斜杠/. 2.字符串结尾符 3.大小端问题 引用标准的Big-Endian和Little-Endian的定义如下：a) Little-Endian就是低位字节排放在内存的低地址端，高位字节排放在内存的高地址端。b) Big-Endian就是高位字节排放在内存的低地址端，低位字节排放在内存的高地址端。 例子: #include stdio.h #include stdlib.h #include netinet/in.h int main(void) { int i_num = 0 printf(i_num:0x%x\n, i_num); printf([0]:0x%x\n, ((char *) i_num + 0)); printf([1]:0x%x\n, ((char *) i_num + 1)); printf([2]:0x%x\n, ((char *) i_num + 2)); printf([3]:0x%x \n\n, ((char *) i_num + 3)); printf([0]:0x%x\n, *((char *) i_num + 0)); printf([1]:0x%x\n, *((char *) i_num + 1)); printf([2]:0x%x\n, *((char *) i_num + 2)); printf([3]:0x%x \n\n, *((char *) i_num + 3)); i_num = htonl(i_num); printf([0]:0x%x\n, ((char *) i_num + 0)); printf([1]:0x%x\n, ((char *) i_num + 1)); printf([2]:0x%x\n, ((char *) i_num + 2)); printf([3]:0x%x \n\n, ((char *) i_num + 3)); printf([0]:0x%x\n, *((char *) i_num + 0)); printf([1]:0x%x\n, *((char *) i_num + 1)); printf([2]:0x%x\n, *((char *) i_num + 2)); printf([3]:0x%x\n, *((char *) i_num + 3)); puts(!!!Hello World!!!); /* prints !!!Hello World!!! */ return EXIT_SUCCESS; } 结果如下： i_num:0xbfc2b83c [0]:0xbfc2b83c [1]:0xbfc2b83d [2]:0xbfc2b83e [3]:0xbfc2b83f [0]:0x78 [1]:0x56 [2]:0x34 [3]:0x12 [0]:0xbfc2b83c [1]:0xbfc2b83d [2]:0xbfc2b83e [3]:0xbfc2b83f [0]:0x12 [1]:0x34 [2]:0x56 [3]:0x78 !!!Hello World!!!
