pszComputerName (PSZ) -
input
Name of computer where port is to be installed.
A NULL string is used for installing a port on the local machine. This parameter
currently must be NULL.
pszPortName (PSZ) - input
Name of printer port to install.
This port, virtual or regular, must not already exist. Following is an example
of a port name: LPT5
pszPortDriver (PSZ) - input
Name of the port driver assigned to this port.
If not NULL, this field must specify an installed port driver; it is case-sensitive.
Following is an example of a port driver: PARALLEL
ulVersion (ULONG) - input
Version of port to create.
Values are as follows:
SPLPORT_VERSION_REGULAR - 0
Creates normal printer
port that can be connected to a print queue. This port will remain after
a reboot.
SPLPORT_VERSION_VIRTUAL - 1
Creates
a virtual printer port that can only be used for querying and setting. This
port exists only until the spooler is disabled or the machine is rebooted.
pBuf (PVOID) - input
Port-driver-specific
buffer.
If SPLPORT_VERSION_VIRTUAL is set, this is a port-driver-specific buffer
that contains information necessary for the port driver to set up a virtual
connection to the printer. There cannot be any imbedded pointers in this
buffer. This buffer wil be passed to the port driver with the BIDI_ADD_VIRTUAL_PORT
command.
cbBuf (ULONG) - input
Length
of the data in pBuf, in bytes.
rc (ULONG) - returns
Return
codes.
- Success
ERROR_DEVICE_IN_USE(99)
Port name is already defined.
ERROR_FILE_NOT_FOUND(2)
Port
driver name is not valid.
ERROR_INVALID_LEVEL(124)
ERROR_INVALID_PARAMETER(87)
An invalid buffer was given.
ERROR_NOT_ENOUGH_MEMORY(8)
Not enough memory to satisfy request.
ERROR_NOT_SUPPORTED(50)
pszComputerName is not supported, or the
port driver does not support the virtual port.
PMERR_SPL_SPOOLER_NOT_INSTALLED(0x4009)
Spooler not enabled; virtual ports require spooler
to be enabled.
