gdb: The F Reply Packet

 
 E.13.4 The 'F' Reply Packet
 ---------------------------
 
 The 'F' reply packet has the following format:
 
 'FRETCODE,ERRNO,CTRL-C FLAG;CALL-SPECIFIC ATTACHMENT'
 
      RETCODE is the return code of the system call as hexadecimal value.
 
      ERRNO is the 'errno' set by the call, in protocol-specific
      representation.  This parameter can be omitted if the call was
      successful.
 
      CTRL-C FLAG is only sent if the user requested a break.  In this
      case, ERRNO must be sent as well, even if the call was successful.
      The CTRL-C FLAG itself consists of the character 'C':
 
           F0,0,C
 
      or, if the call was interrupted before the host call has been
      performed:
 
           F-1,4,C
 
      assuming 4 is the protocol-specific representation of 'EINTR'.
