.TH CD_ABORT_OUTPUT_REQ 7 "2004/01/12 23:45:07" "LiS-2_16_18-8" "Linux STREAMS"
.SH NAME
.B CD_ABORT_OUTPUT_REQ
\- abort output
.SH SYNOPSIS
This primitive consists of one
.B M_PROTO
or
.B M_PCPROTO
message block structured as follows:
.sp
.nf
\fC\s-1\
typedef struct {
    cd_ulong cd_primitive;
} cd_abort_output_req_t;
\fR\s+1
.fi
.SH DESCRIPTION
This user originated primitive requests that any transmission operation currently in
progress be aborted.
.SS Parameters
This primitive contains the following parameters:
.TP
.I cd_primitive
Specifies the primitives type.
.SS State
This primitive is valid in any state in which the output section is enabled,
but no local acknowledgment is pending.  The new state remains unchanged
unless the current state is
.BR CD_OUTPUT_ACTIVE ,
in which case the new state is
.B CD_ENABLED
or
.BR CD_INPUT_ALLOWED ,
depending on the state of the input section.
.SH RESPONSE
This primitive requires the CD provider to acknowledge receipt of the
primitive as follows:
.PP
.B "Successful:"
Upon success, the provider acknowledges the receipt of the primitive with the
.BR CD_OK_ACK (7)
primitive.  The new state is unchanged.
.PP
.B "Unsuccessful (non-fatal errors):"
Upon failure, the provider acknowledges the receipt of the primitive with the
.BR CD_ERROR_ACK (7)
including the reaons for failure.  The new state remains unchanged.
.PP
.B Note:
if the output section is not active at the time that the
.B CD_ABORT_OUTPUT_REQ
is issued, but the communications device is enabled, the provider should
discard the
.B CD_ABORT_OUTPUT_REQ
primitive and not issue any non-fatal error.
