篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了C-调试断言失败:_CrtIsValidHeapPointer(block)相关的知识,希望对你有一定的参考价值。
我正在尝试使用VS2019从C中的.csv文件读取,并收到断言错误。我收到的断言错误是_CrtIsValidHeapPointer,我认为它与内存泄漏有关,但我无法意识到是什么触发了它。
任何帮助将不胜感激。
我的结构看起来像这样:
struct movie
double score;
char* title;
int year;
char* actors;
char* genre;
;
我的功能是:
void readMoviesFromCSV(movie* movies)
FILE* inputFile;
fopen_s(&inputFile, "Movies.csv", "r");
if (inputFile == NULL)
fclose(inputFile);
printf("Error opening file.\n");
exit(1);
char* lineBuffer = (char*)calloc(sizeof(char), 2048);
char* current = (char*)calloc(sizeof(char), 512);
fgets(lineBuffer, 2048, inputFile); // Discarding of the header
for (int i = 0; i < numberOfMovies; i++)
fgets(lineBuffer, 2048, inputFile);
current = strtok_s(lineBuffer, ",", &lineBuffer);
(movies + i)->score = atof(current);
current = strtok_s(lineBuffer, ",", &lineBuffer);
strcpy_s((movies + i)->title, 512, current);
current = strtok_s(lineBuffer, ",", &lineBuffer);
(movies + i)->year = atoi(current);
current = strtok_s(lineBuffer, ",", &lineBuffer);
strcpy_s((movies + i)->actors, 512, current);
current = strtok_s(lineBuffer, "\n", &lineBuffer);
strcpy_s((movies + i)->genre, 512, current);
printf("ID: %d\nScore: %.2lf\nTitle: %s\nYear: %d\nActors: %s\nGenre: %s\n\n", i + 1, (movies + i)->score, (movies + i)->title, (movies + i)->year, (movies + i)->actors, (movies + i)->genre);
free(lineBuffer);
free(current);
fclose(inputFile);
return;
我在main中分配了电影数组:
int main()
movie* movies = (movie*)calloc(sizeof(movie), numberOfMovies);
for (int i = 0; i < numberOfMovies; i++)
(movies + i)->title = (char*)calloc(sizeof(char), 512);
(movies + i)->actors = (char*)calloc(sizeof(char), 512);
(movies + i)->genre = (char*)calloc(sizeof(char), 512);
readMoviesFromCSV(movies);
// free(movies);
return 0;
这里可能是什么问题?
答案
至少此行是错误的:
