C语言字符串分割

strsep函数用于分解字符串为一组字符串。定义语句为char *strsep(char **stringp, const char *delim);

使用实例：

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

int main()
{
    char str[] = "$GPFPD,2005,266904.450,274.162,-1.111,0.504,40.1917161,116.0636047,132.93,0.011,-0.002,0.003,-1.000,16,13,0B*21";
    
    char *buf;
    buf =str;

    printf("buf=%s\n",buf);
    char *token;
    while((token = strsep(&buf,",")) != NULL)
    {
	printf("%s\n",token);
    }
   	 
    return 0;

}

输出结果：

buf=$GPFPD,2005,266904.450,274.162,-1.111,0.504,40.1917161,116.0636047,132.93,0.011,-0.002,0.003,-1.000,16,13,0B*21
