No. In fact, the calls already overwrite the DOS memory the pattern is copied to, on the next call to either function. > - Is it safe calling findfirst() & co. multiple times, Should be, if DOS allows it. We copy the ffblk data down to dos memory, do the call, then copy the data back up to djgpp memory. These functions just call the DOS interrupt services after moving the data around, so whatever DOS allows, DJGPP allows also.
