2017年1月24日 · The other one is being able to set breakpoints beforehand, to "analyze the effects". GDB's default behaviour is to run the program as a child process, thus using the same standard streams. So it is impossible to write to the child's stdin while being in GDB's CLI because, at this moment, it is being read by GDB, not your program.
