a function to get the full path names of a list of files

[redstone-cold]

First ,I am not a C++ programmer but a python programmer .I am only a little familiar with C++ ,so I cannot implement this function myself ,my use of this function is to wrap it into Python to improve my program’s working efficiency .

I have already know a list of files in a specified directory or its subdirectories , I need a function to get the full path names of this list of files ,now I am going to give out the prototype of this function , I wonder if you can help me to implement this function .

function name : get FullPathNames
parameter : the path to the parent directory that all of that list of filesare contained in, a list of file names the I need to get their full path names back

return value : a list of full path names

thanks in advance !

I use it on WinXP

Luca gave you an answer, but I really doubt you'll gain anything by
rewriting your python code (presumably something like
"[os.path.join(parent,path) for path in paths]") in C++. Except of
course if your only goal is to learn something new.

If it is some homework then ... that was meant for you to learn
something, why you ask us to spoil the purpose for you?

If you need it as Python programmer then you should not implement it
in C++ to use it in Python. Additional layer of C++ between your
Python code and operating system wins you nothing. Same written in
Python works as quickly.

All the functionality you asked is already present in file system
kernel of operating system. I am not sure if it is implemented in C,
C++, assembler or in mix of those but majority of running time of it
will go to I/O operations of hard drive driver.
