	Called in response to the example command-line application's -o (output) switch, this function is used to override any value of `/PageBufferType` from the page device. If the existing value is `"LE"`, then the override will be performed silently; for other values, a warning will be issued.

static sw_event_result	monitor_channel (void ctx, sw_event evt)
	Monitor through events contextualisation. The core performs transcoding of unrecognised encodings to the Unicode Private Use Area, so event messages are always UTF-8. The fallback monitor handler, which writes event messages to the %monitor% device, undoes the transcoding, providing the raw bytes to device write. Rather than repeat that detection and decoding here, we install a monitor handler that picks the output channel that the %monitor% device will use, and calls the rest of the event handler chain. This is compatible with the colour monitor handler.

	Wrapper for HqCustomTrace() to ensure output goes to the stderr channel, rather than the stdout channel, when using the monitor file callback.

void	jsonSavePS (void)
	Enable saving of PostScript representation of JSON config files.

void *	CurrentJobContext (void)
	Return the job context attached to the currently processing job. This is the job context pointer provided to raster callbacks, initially created by the input queue job submission.

#define DEVICE_MOUNT_PS ( dev_ )

  "mark {\n"                                                            \

  "} stopped cleartomark\n"

PostScript to mount a non-filesystem device (no /Prefix).

If the device is already mounted we make sure it is also enabled. This is a format string, so percent characters are doubled. All of the parameters we are setting are non device-specific, so we can unconditionally mount and set the parameters.

Function Documentation

◆ configureSocketDevice()

static HqBool configureSocketDevice	(	const char *	pszAddress,
		int32	nPort
	)

static

Set the IP address and port number used when outputting to the socket device.

Parameters

pszAddress	An IP address (nnn.nnn.nnn.nnn).
nPort	The port number to use.

Returns: TRUE on success.

◆ discardStream_Bytes()

static int32 discardStream_Bytes	(	void *	pPrivate,
		Hq32x2 *	pBytes,
		int32	reason
	)

static

'Bytes' method for the data-discarding write stream.

Always returns FALSE as data is not available to be read back and the total size is unknown.

◆ discardStream_Seek()

static int32 discardStream_Seek	(	void *	pPrivate,
		Hq32x2 *	destination,
		int32	flags
	)

static

'Seek' method for the data-discarding write stream.

Seeking on the discard stream always succeeds, but usually has no effect. For the special case of seeking by zero relative to the current stream position, the function will update the destination parameter with the number of bytes that were written since the discard stream was opened.

◆ discardStream_Write()

static int32 discardStream_Write	(	void *	pPrivate,
		uint8 *	buff,
		int32	len
	)

static

'Write' method for the data-discarding write stream.

We update the count of bytes written and discard the input data.

◆ monitorFileWrite()

static void monitorFileWrite	(	uint32	buflen,
		const uint8 *	buffer,
		HqBool	do_flush,
		FileDesc *	fd
	)

static

Helper function for monitorFile.

◆ monitorStderr()

static void monitorStderr	(	uint32	buflen,
		const uint8 *	buffer
	)

static

Default monitor callback to route all messages to stderr.

Parameters

	buflen	The length of the message to output.
[in]	buffer	A buffer of data to output. This is written to stderr verbatim.

This is installed on startup by init_C_runtime_skintest() so we don't lose any output.

◆ MountAllDrives()

static HqBool MountAllDrives ( void )

static

Run a sequence of PostScript control jobs through the RIP to mount all of the available filesystem routes as file devices.

Generate the PostScript that will mount drives. This allows PostScript to be submitted to the RIP which refers to any drive. For example, the way in which PDF files are submitted need to be done by a control job, and that control job needs to reference the PDF file, and it might be on one of these drives.

This must be called after having started the RIP.

Returns: TRUE if all drives were mounted successfully, otherwise FALSE.

◆ MountOtherDevices()

static HqBool MountOtherDevices ( SkinDynamicBuffer * mount )

static

Generate the PostScript that will mount other devices including ram and jobtmp.

The jobtmp device provides a temporary storage area whose contents may (or may not) be cleared by external client code in between jobs. This device is only mounted when the SW resources folder is read-only, or compiled into RAM. The purpose of this device is to provide an alternative to tmp, which will actually be backed by RAM in these cases. The jobtmp device is mounted explicitly as a disk volume. The skin pagebuffer (PGB) device in particular takes advantage of this. See KGetBandCacheDev() in pgbdev.c.

◆ RegisterAlternateCMMs()

static HqBool RegisterAlternateCMMs ( void )

static

Registers the alternate Color Management Modules to be made available to the RIP.

Returns: TRUE if all modules were registered successfully, and FALSE otherwise.

See also: SwRegisterCMM()

◆ registerDiscardStreamWriter()

static HqBool registerDiscardStreamWriter ( HqnWriteStream * pWriteStream )

static

Configure the specified data-discarding write stream object, and register it using registerStreamWriter().

Returns: TRUE on success, FALSE otherwise.

◆ RegisterHandlers()

static HqBool RegisterHandlers ( void )

static

Registers the event handlers to be made available to the RIP.

Returns: TRUE if all handlers were registered successfully, and FALSE otherwise.

See also: SwRegisterHandlers()

◆ RegisterHTMs()

static HqBool RegisterHTMs ( void )

static

Registers the halftone modules to be made available to the RIP.

Returns: TRUE if all modules were registered successfully, and FALSE otherwise.

See also: SwRegisterHTM()

◆ RegisterRasterBackends()

static HqBool RegisterRasterBackends ( void )

static

Registers the raster backend handlers to be made available to the RIP.

Return values

TRUE	All raster backend handlers were registered successfully
FALSE	If any raster backend handler was not registered

◆ ValidateOutputTargetAndDestination()

static HqBool ValidateOutputTargetAndDestination	(	const uint8 *	pOutputTarget,
		const char *const	valid_targets[]
	)

static

Check for invalid combinations of output target/destination.

Returns: TRUE if the combination is valid.

Variable Documentation

◆ mon_channel_key

pthread_key_t mon_channel_key

static

Channel (FILE) to send raw output to. This is a per-thread key because the expectation is that an event or wrapper function will contextualise output channel, then ultimately

◆ mon_handlers

sw_event_handlers mon_handlers[]

static

Initial value:

= {
  { monitor_channel,   ((void*)0) , 0, SWEVT_MONITOR, MON_PRE_DEFAULT},
  { monitor_fallback,  ((void*)0) , 0, SWEVT_MONITOR, MON_FALLBACK - 100},
}

Event handlers for monitor through events. We register two channels, one just before the default handler to handle contextualisation of the monitor channel, and the other as a fallback to the RIP's fallback. If the RIP is not running, we just send output directly to the default monitor callback installed.
