#include <dos.h> int setftime(int handle, struct ftime *ftimep);
This function sets the modification time of a file. Note that since writing to a file and closing a file opened for writing also sets the modification time, you should only use this function on files opened for reading.
See section getftime, for the description of struct ftime
.
Zero on success, nonzero on failure.
