Question

由于某种原因，我收到错误：'dlist_init'：调用的参数太少。这是我的主要内容。我没有看到我的dlist_init有什么问题，或者我在main.dlist_init中使用它初始化了双链表。这些函数位于main之后的数据文件中。

#include <stdlib.h>
#include <stdio.h>
#include <string.h>
//#include "bool.h"
#include "Dlinklist.h"
#include "DlistElmt.h"
#include "Dlist.h"
#include "Dlistdata.h"

   /**************************************************************************************************/

int main ( int argc, char *argv[] )
{
    FILE *ifp, *ofp;
    //char outputFilename[] = argv[2];
    int *hour, *min;
    Dlist *list;
    float *temp;
    char line[15];

    if ( argc != 3 ) /* argc should be 3 for correct execution */
    {
        /* We print argv[0] assuming it is the program name */
        printf( "usage: %s filename", argv[0] );
    }
    else 
    {
        // We assume argv[1] is a filename to open
        ifp = fopen( argv[2], "r" );

        if (ifp == 0 ){

            printf("Could not open file\n");
        }

        else{

            ofp = fopen(argv[2], "w");

            dlist_init(list);

            while (fscanf(ifp, "%d:%d %f ", &hour, &min, &temp) != EOF) {
            //while( fgets(line, 100, ifp)){
                puts(line);
                fprintf(ofp, "%s", line);
                //if(sscanf("%d:%d %df", &hour, &min, &temp)==3){

                //}
            }

假设函数原型在您的一个头文件中声明 - 它是否与您提供的声明匹配？

Visual Studio为我编译错误：要调用的参数太少
