swapbytes C-mex function swapbytes is a self-building C-mex function that mimics the MATLAB intrinsic function of the same name, reversing the byte ordering of each element in array X1, X2, ..., converting little-endian values to big-endian (and vice versa). Mai... J Tursa 被引量:...
嵌入式软件开发时,大小端字节序和Byte Swap是很常见的事情,许多工具软件诸如Modbus Poll和Modbus Slave都提供了数值(short,unsigned short,int, unsigned int,long long,unsigned long long,float,double等数值)的4种表示方式:Big-endian(大端)、Little-endian(小端)、Big-endian byte swap、Little-endian byte swap...

考虑到网络字节序为big-endian,修改程序来比较一下Host Byte Order和Internet Byte Order的区别。 /* * filename: byteorder.c */#include <stdio.h>#include <netinet/in.h>union { short s; char c[sizeof(short)];}un;short test = 0x0203;void byteorder(char *msg){ printf("%s", msg); if...

在计算机科学领域中字节序是指存放多字节数据的字节byte的顺序典型的情况是整数在内存中的存放方式和网络传输的传输顺序 Fortran对无格式文件的大小端(big_endianlittle_endian)转换 Fortran对无格式文件的大小端(big_endian & little_endian)转换 字节序,又称端序,尾序,英文:Endianness。在计算机科学领域中,字节序是...
