I am attempting to reverse-engineer an old DOS executable, which seems to have been compiled around 1992 using Microsoft's C compiler at the time.
When opening the executable in Ghidra no imports are listed, so I assume that any library functions that were utilised have been statically linked. Certain strings exist such as
%s%s, so I can assume that
printf has been utilised, for example.
However, when looking through the code, nothing stands out as obviously being library code. Is there a way to identify library functions just from looking at the assembly/decompiled output?
