错误：在 C 语言中'tWordInfo'之前执行声明说明符或'...'

Question

我在C中有这3个文件，一个是头文件，另一个是dictionary.C，最后一个是main.C

dictionary.c

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

/* Calculate the edition distance between two strings */
int getDistance(char* ref,char* word) {
char* w1=NULL;
char* w2=NULL;
int dist=0;
int i=0;
bool different=false;
/* Put the shortest word on w1 and the longest on w2. */
if(strlen(ref)<=strlen(word)) {
    w1=ref;
    w2=word;
} else {
    w1=word;
    w2=ref;
}
/* Copare char to char */
for(i=0;i<strlen(w2);i++) {
    if(different) {
        /* If the words are different, increase the distance */
        dist++;
    } else {
        /* Compare the new char and word lenghts */
        if(i<strlen(w1)) {
            different=w1[i]!=w2[i];
        } else {
            /* w1 is shorter than w2 */
            different=true;
        }
        if(different) {
            /* If the words are different, increase the distance */
            dist++;
        }
    }
}
return dist;
}
/* Get word information */
bool getWordInfo(char* str,char* word,int* languageID,int* wordID){
    *languageID=-1;
    *wordID=-1;
    sscanf(str,"%s ; %d ; %d",word,languageID,wordID);
    return *languageID>0 && *wordID>0;
}
WordList create(){
    WordList l;
    l.act = 1;
    l.nelem = 0;
    return l;
};
WordList insert(WordList l, tWordInfo e){
    int i;
    if (l.nelem == [250]){
        printf("error");
    }else{
        for (i=l.nelem; l.act; i--){
            l.WordInfo[i+1]= l.WordInfo[i];
        }
        l.WordInfo[l.act]= e;
        l.nelem = l.nelem + 1;
        l.act = l.act + 1;
    }
    return l;
}

dictionary.h

/* Declare the boolean type */
typedef enum {false, true} bool;

/* Calculate the edition distance between two strings */
int getDistance(char* ref,char* word);
/* Get word information */
bool getWordInfo(char* str,char* word,int* languageID,int* wordID);
char tWordInfo(int* languageID, int* wordID, char* word[128]);
typedef struct {
    char tWordInfo[250];
    int act;
    int nelem;
}tWordList, WordList;
WordList create(); 
WordList insert(WordList l, tWordInfo e);

和最后一个主要的。c

#include <stdio.h>
#include "dictionary.h"
int main(int argc, char **argv)
{
    char word1[128];
    char word2[128];
    int langId1,wordId1;
    int langId2,wordId2;
    int d1,d2; 
    WordList l;
    tWordInfo e;
    create();
    printf("%dn", l.act);
    printf("%sn", l.tWordInfo[l.act]);
    printf("%dn", l.nelem);
    getWordInfo("hospital ; 1 ; 1",word1,&langId1,&wordId1);
    getWordInfo("hola ; 1 ; 2",word2,&langId2,&wordId2);
    d1=getDistance(word1,word2);
    d2=getDistance(word2,word1);
    printf("[%d,%d] => %sn",langId1,wordId1,word1);
    printf("[%d,%d] => %sn",langId2,wordId2,word2);
    printf("d(%s,%s)=%dn",word1,word2,d1);
    printf("d(%s,%s)=%dn",word2,word1,d2);
    return 0;
}

程序尚未结束，但我无法定义函数insert，在字典文件（.c和.h）中，会出现以下错误：未预期的声明说明符或"…"在"tWordInfo"之前，那么这里的问题是什么？我该如何解决？

另一个问题是，l.act和l.nelem的printf没有给我1和0的值，给l.act-2，给l.nelem一个大数字。为什么？

感谢

TWordInfo被声明为一个函数，然后在插入函数中用作参数类型。该参数需要不同的类型。
