NCBCANCEL

NCBCANCEL

This command cancels a previous outstanding command. The ncb_buffer field points to the NCB structure with the operation that you want canceled. Canceling an NCBSEND or NCBCHAINSEND command aborts the session; however, aborting their no-ack variants does not cancel their respective sessions. The following commands cannot be canceled: NCBADDGRNAME, NCBADDNAME, NCBCANCEL, NCBDELNAME, NCBRESET, NCBDGSEND, NCBDGSENDBC, and NCBSSTAT. Table 22-5 describes the characteristics of the NCBCANCEL command.
