First, please in the future try to deal with one subject in each
message.  Otherwise, you make the thread very difficult to read.

Is it a C++ program?  If so, you need to declare the function ``extern "C"''.
If it is a C program, please post here the shortest complete program
that can be used to reproduce the effect, and please tell what do you
mean by "has no effect at all".

You cannot ``write back'' the info from findfirst, you need to call
specialized functions for that.  For example, to change file's times,
use the library functioin `utime', to change file's attributes, use
`chmod', etc.

There is no library function for this, at the moment.  You can use
__dpmi_int to invoke subfunction 1 of function 7160h of interrupt 21h,
which will do that.  Ralf Brown's Interrupt List has the details.

One way is to call the library function `glob' passing it the wildcard
".../*" as its argument.  But please note that "..." is a special
feature of DJGPP which will not work on any other platform, and `glob'
is only portable to Unix/Linux, other DOS/Windows compilers generally
don't have it.
