代码如下

#include<stdio.h>
#include<string.h>
#include<stdlib.h>
int msg_deal(char *msg_src, char *msg_done[],char *str)//返回切割了多少次
{
    msg_done[0] = msg_src;
    int i = 0;
    while((msg_done[i] = strtok(msg_done[i], ",")) && ++i);
    return i;
}
int main(int argc, char const *argv[])
{
    char msg_src[]="+CMGR:REC UNREAD,+8613466630259,98/10/01,18:22:11+00,ABCdefGHI";
    char *msg_done[28] = {NULL};
    char *str = NULL;

    int num = msg_deal(msg_src, msg_done, str);
    *(msg_done[3]+strlen(msg_done[3])-3) = '\0';
    /*
    char * ret = strstr(msg_done[3], "+");
    if (ret != NULL)
    {
        *ret = '\0';
    }
    else
    {
        printf("ret is NULL\n");
    }
    */

    printf("%s\n", msg_done[0]);
    printf("%s\n", msg_done[1]);
    printf("%s\n", msg_done[2]);
    printf("%s\n", msg_done[3]);
    printf("%s\n", msg_done[4]);
    return 0;
}

运行结果如下
