C++ c++;斯堪的纳维亚正在填满我的记忆
我使用在我的类中实现的函数:C++ c++;斯堪的纳维亚正在填满我的记忆,c++,file,ram,scandir,C++,File,Ram,Scandir,我使用在我的类中实现的函数: bool MyClass::getNextFile(string& s_first_file, const char* c_path_data){ //string s_first_file = ""; struct dirent **namelist; string s_file_actual = ""; int n; int i=0; n = scandir(c_path_data, &nameli
bool MyClass::getNextFile(string& s_first_file, const char* c_path_data){
//string s_first_file = "";
struct dirent **namelist;
string s_file_actual = "";
int n;
int i=0;
n = scandir(c_path_data, &namelist, dataFilter, alphasort);
if (n < 0){
//perror("scandir");
return false;
}else{
while (i<n) {
s_file_actual = namelist[i++]->d_name;
if(i==1){
cout << "get file " << s_file_actual << "..." << endl;
s_first_file = s_file_actual;
}
}
free(namelist[i-1]);
return true;
}
}
bool MyClass::getNextFile(字符串&s\u第一个文件,常量字符*c\u路径数据){
//字符串s_first_file=“”;
结构目录**名称列表;
字符串s_file_actual=“”;
int n;
int i=0;
n=scandir(c_路径_数据、名称列表、数据过滤器、字母排序);
if(n<0){
//佩罗(“斯堪的纳维亚”);
返回false;
}否则{
while(id_name;
如果(i==1){
coutwhile(id\u name;
如果(i==1){
难道你应该这样做吗
while (i<n)
{
s_file_actual = namelist[i++]->d_name;
if (i==1)
{
cout << "get file " << s_file_actual << "..." << endl;
s_first_file = s_file_actual;
}
free(namelist[i-1]);
}
free(namelist);
return true;
while(id\u name;
如果(i==1)
{
cout看起来您正在释放namelist
的内容,但没有释放namelist
本身。代码转储没有向我解释问题或修复=-1。
while (i<n) {
s_file_actual = namelist[i++]->d_name;
if (i==1) {
cout << "get file " << s_file_actual << "..." << endl;
s_first_file = s_file_actual;
}
}
free(namelist[i-1]);
return true;
while (i<n)
{
s_file_actual = namelist[i++]->d_name;
if (i==1)
{
cout << "get file " << s_file_actual << "..." << endl;
s_first_file = s_file_actual;
}
free(namelist[i-1]);

free(namelist);
return true;
