Synopsis

#include <stropts.h>

Description

The <stropts.h> header defines the bandinfo structure, which includes the following members:

unsigned char bi_pri     /* priority band */
int           bi_flag    /* flushing type */

The <stropts.h> header defines the strpeek structure that includes the following members:

struct strbuf ctlbuf     /* control portion of the message */
struct strbuf databuf    /* data portion of the message */
t_uscalar_t   flags      /* RS_HIPRI or 0 */

The <stropts.h> header defines the strbuf structure that includes the following members:

int  maxlen     /* maximum buffer length */
int  len        /* length of data */
char *buf       /* pointer to buffer */

The <stropts.h> header defines the strfdinsert structure that includes the following members:

struct strbuf ctlbuf     /* control portion of the message */
struct strbuf databuf    /* data portion of the message */
t_uscalar_t   flags      /* RS_HIPRI or 0 */
int           fildes     /* file descriptor of the other STREAM */
int           offset     /* relative location of the stored value */

The <stropts.h> header defines the strioctl structure that includes the following members:

int  ic_cmd        /* ioctl() command */
int  ic_timout     /* timeout for response */
int  ic_len        /* length of data */
char *ic_dp        /* pointer to buffer */

The <stropts.h> header defines the strrecvfd structure that includes the following members:

int   fda     /* received file descriptor */
uid_t uid     /* UID of sender */
gid_t gid     /* GID of sender */

The uid_t and gid_t types are defined through typedef as described in <sys/types.h>. See types.h(3HEAD).

The <stropts.h> header defines the t_scalar_t and t_uscalar_t types, respectively, as signed and unsigned opaque types of equal length of at least 32 bits.

The <stropts.h> header defines the str_list structure that includes the following members:

int              sl_nmods        /* number of STREAMS module names */
struct str_mlist *sl_modlist     /* STREAMS module names */

The <stropts.h> header defines the str_mlist structure that includes the following member:

char l_name[FMNAMESZ+1]

a STREAMS module name

The following macros are defined for use as the request argument to ioctl():

I_PUSH

Push a STREAMS module.

I_POP

Pop a STREAMS module.

I_LOOK

Get the top module name.

I_FLUSH

Flush a STREAM.

I_FLUSHBAND

Flush one band of a STREAM.

I_SETSIG

Ask for notification signals.

I_GETSIG

Retrieve current notification signals.

I_FIND

Look for a STREAMS module.

I_PEEK

Peek at the top message on a STREAM.

I_SRDOPT

Set the read mode.

I_GRDOPT

Get the read mode.

I_NREAD

Size the top message.

I_FDINSERT

Send implementation-defined information about another STREAM.

I_STR

Send a STREAMS ioctl().

I_SWROPT

Set the write mode.

I_GWROPT

Get the write mode.

I_SENDFD

Pass a file descriptor through a STREAMS pipe.

I_RECVFD

Get a file descriptor sent via I_SENDFD.

I_LIST

Get all the module names on a STREAM.

I_ATMARK

Is the top message ``marked''?

I_CKBAND

See if any messages exist in a band.

I_GETBAND

Get the band of the top message on a STREAM.

I_CANPUT

Is a band writable?

I_SETCLTIME

Set close time delay.

I_GETCLTIME

Get close time delay.

I_LINK

Connect two STREAMs.

I_UNLINK

Disconnect two STREAMs.

I_PLINK

Persistently connect two STREAMs.

I_PUNLINK

Dismantle a persistent STREAMS link.

The following macro is defined for use with I_LOOK:

FMNAMESZ

minimum size in bytes of the buffer referred to by the arg argument

The following macros are defined for use with I_FLUSH:

FLUSHR

flush read queues

FLUSHW

flush write queues

FLUSHRW

flush read and write queues

The following macros are defined for use with I_SETSIG:

S_RDNORM

A normal (priority band set to 0) message has arrived at the head of a STREAM head read queue.

S_RDBAND

A message with a non-zero priority band has arrived at the head of a STREAM head read queue.

S_INPUT

A message, other than a high-priority message, has arrived at the head of a STREAM head read queue.

S_HIPRI

A high-priority message is present on a STREAM head read queue.

S_OUTPUT

The write queue for normal data (priority band 0) just below the STREAM head is no longer full. This notifies the process that there is room on the queue for sending (or writing) normal data downstream.

S_WRNORM

Equivalent to S_OUTPUT.

S_WRBAND

The write queue for a non-zero priority band just below the STREAM head is no longer full.

S_MSG

A STREAMS signal message that contains the SIGPOLL signal reaches the front of the STREAM head read queue.

S_ERROR

Notification of an error condition reaches the STREAM head.

S_HANGUP

Notification of a hangup reaches the STREAM head.

S_BANDURG

When used in conjunction with S_RDBAND, SIGURG is generated instead of SIGPOLL when a priority message reaches the front of the STREAM head read queue.

The following macro is defined for use with I_PEEK:

RS_HIPRI

Only look for high-priority messages.

The following macros are defined for use with I_SRDOPT:

RNORM

Byte-STREAM mode, the default.

RMSGD

Message-discard mode.

RMSGN

Message-non-discard mode.

RPROTNORM

Fail read() with [EBADMSG] if a message containing a control part is at the front of the STREAM head read queue.

RPROTDAT

Deliver the control part of a message as data when a process issues a read()

RPROTDIS

Discard the control part of a message, delivering any data part, when a process issues a read()

The following macro is defined for use with I_SWOPT:

SNDZERO

Send a zero-length message downstream when a write() of 0 bytes occurs.

The following macros are defined for use with I_ATMARK:

ANYMARK

Check if the message is marked.

LASTMARK

Check if the message is the last one marked on the queue.

The following macro is defined for use with I_UNLINK:

MUXID_ALL

Unlink all STREAMs linked to the STREAM associated with fildes.

The following macros are defined for getmsg(), getpmsg(), putmsg(), and putpmsg():

MSG_ANY

Receive any message.

MSG_BAND

Receive message from specified band.

MSG_HIPRI

Send/receive high-priority message.

MORECTL

More control information is left in message.

MOREDATA

More data is left in message.

The <stropts.h> header can make visible all of the symbols from <unistd.h>.
