c906108c | 536 | |
c5aa993b JM |
537 | 1) Fork, and have have one fork handle the to user direction, |
538 | and have the other hand the to target direction. This | |
539 | obviously won't cut it for MSDOS. | |
c906108c | 540 | |
c5aa993b JM |
541 | 2) Use something like select. This assumes that stdin and |
542 | the target side can both be waited on via the same | |
543 | mechanism. This may not be true for DOS, if GDB is | |
544 | talking to the target via a TCP socket. | |
