c - 将数组或结果或数组返回到主函数 C

Question

嗨，我有一个小功能，可以从句子中删除以 2 个辅音开头的单词。有这样的功能:

char * fun_zod(char * sak)
{
    char * sep = " "; //Zodziu atskirejas - tarpas
    char * zodis = strtok(sak,sep); //Nurodome kad sakini suskirstytume i zodzius po viena
    char * zodmas[20];
    int i = 0;
    zodmas[0] = zodis;   //Iraso atskirai kiekviena zodi i masyva
    while (zodis != NULL)
    {
        if (zodis == NULL)
        break;
        i++;
        zodis = strtok(NULL,sep);
        zodmas[i] = zodis;
    }
    int n=i;
    for(int j = 0;j < n;j++)
    {
       if (!( zodmas[j][0] == 'a' || zodmas[j][0] == 'e' || zodmas[j][0] == 'i' || zodmas[j][0] == 'o' || zodmas[j][0] == 'u' ) && !( zodmas[j][1] == 'a' || zodmas[j][1] == 'e' || zodmas[j][1] == 'i' || zodmas[j][1] == 'o' || zodmas[j][1] == 'u' ))
       {
           zodmas[j]="";
       }

    }
    for (i=0;i < n; i++)
    {
        printf("%s ", zodmas[i]);
    }
}

现在我想将结果返回到主函数，不是从函数打印结果，而是从主函数打印结果。我知道在 C 中我不能从函数返回数组。也许有人可以建议我如何将结果返回到主函数？感谢您的帮助

传递 zodmas 和 n 作为参数。

添加一个测试以防止 zodmas 溢出

char * fun_zod(char * sak, int *n, char **zodmas)                              
{                                                                              
    char * sep = " "; //Zodziu atskirejas - tarpas                             
    char * zodis = strtok(sak,sep); //Nurodome kad sakini suskirstytume i zodzius po viena 
    int i = 0;                                                                 
    zodmas[0] = zodis;   //Iraso atskirai kiekviena zodi i masyva              
    while (zodis != NULL && i < *n)                                            
    {                                                                          
        if (zodis == NULL)                                                     
            break;                                                             
        i++;                                                                   
        zodis = strtok(NULL,sep);                                              
        zodmas[i] = zodis;                                                     
    }                                                                          
    *n=i;                                                                      
    for(int j = 0;j < i;j++)

        {
