i am trying to use dirent.h to check whether a file is present in a directory but it is not returning anything

Question

void exist(std::string location) {
// if error occurs false will be returned
bool exists = false;

DIR *dir = NULL;
dirent *entry;

try {
if(dir==NULL)
dir = opendir(location.c_str());

while((entry = readdir(dir))!=NULL) {
if(strcmp(location.c_str(),entry->d_name))
exists = true;
}
}catch(int x) {
std::cout<<"error"<<std::endl;
}
std::cout<<exists<<std::endl;
}

is something wrong in the code which checks whether files is present in directory or not?

Answer 1

why you not try to open file normally. if the file is doesnt exist, it will throw an error

Answer 2

write in correct format
