gdb io buffer and debugged programme's io buffer

[horse_rivers]

hi,

when I start  gdb in emacs  and  run my  executable  file  ,  the  output  of  
debuged  programme  will be  showed  in  a  seperate  buffer ,

which I feel   discomfort, how to make  its  output  shared  with  gdb's  own 
buffer?


thanks!
