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

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?

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