Hi all,

I need a logic for checking the directory for a file if a file exists i need to store the file name to a variable

for example:-

i am having a directory called "test", initially it is empty, i need to continuously check this directory for a file if any file is present in the directory for eg: if it contains "name.txt"
file
i need to store this name to a variable like below

char *buff;
buff = name.txt;


can any plz suggest any idea, i have a logic for checking the directory but i do know how to take a filename and to store that in a variable

Thanks
