      - bdeAutoCorrectLinks
        Takes diagram and auto corrects the links so that they all create orthogonal angles with one another.
      - bdeCreateActivationLink
        Creates an activation link between srcBlock and destBlock. Connects two blocks with ports of type activation.
      - bdeCreateBusLink
        Creates a bus link between srcBlock and destBlock. Can link to other bus ports and explicit ports. Does not make an interferance block automatically when trying to connect bus port to implicit ports. Cannot connect to activation ports.
      - bdeCreateExplicitLink
        Creates an explicit link between srcBlock and destBlock. Can connect to other explicit ports and bus ports. Does not make an interferance block automatically when trying to connect explicit port to implicit ports.
      - bdeCreateImplicitLink
        Creates an implicit link between srcBlock and destBlock. Does not make an interferance block automatically when trying to connect an implicit port to explicit ports. Can connect implicit and explict ports in the ui but through the api you must connect an implicit port to an implicit port.
      - bdeGetActivationLink
        Returns an activation link in the diagram that is part of block. Can only link to other ports that are activation ports.
      - bdeGetBusLink
        Returns a bus link in the diagram that is part of block.
      - bdeGetExplicitLink
        Returns an explicit link in the diagram that is part of block.
      - bdeGetImplicitLink
        Returns an implicit link in the diagram that is part of block.
      - bdeGetLinkColor
        Returns the color of a given link.
      - bdeGetLinkDestinationBlock
        Returns the destination block of a given link.
      - bdeGetLinkDestinationBlockName
        Returns the name of a destination block of a given link.
      - bdeGetLinkDestinationPort
        Returns the destination port of a given link.
      - bdeGetLinkDestinationPortNumber
        Returns the destination port number of a given link.
      - bdeGetLinkDestinationPortType
        Returns the destination port IO type of a given link.
      - bdeGetLinkIntermediatePoints
        Returns the intermediate points of a given link.
      - bdeGetLinkSourceBlock
        Returns the source block of a given link.
      - bdeGetLinkSourceBlockName
        Returns the name of a source block of a given link.
      - bdeGetLinkSourcePort
        Returns the source port of a given link.
      - bdeGetLinkSourcePortNumber
        Returns the source port number of a given link.
      - bdeGetLinkSourcePortType
        Returns the source port IO type of a given link.
      - bdeGetLinkThickness
        Returns the thickness of a given link.
      - bdeGetLinkType
        Returns the type of a given link.
      - bdeSetLinkColor
        Sets the color of a link. Red is for activation links, green is for bus links, blue is for implicit links and explicit links are the rgba value of 64, 64, 64, 255.
      - bdeSetLinkIntermediatePoints
        Sets the points for a given link to pass through.
      - bdeSetLinkThickness
        Sets the thickness of a link.

bdeGetLinkSourcePortNumber

Returns the source port number of a given link.

Syntax

srcPortNumber = bdeGetLinkSourcePortNumber(link)

Inputs

link: The link to get the source port number of.; Type: hwdcConnection

Outputs

srcPortNumber: The source port number of the link.; Type: integer

Examples

Get the source port number of a given link:


          diagram = bdeGetCurrentDiagram();
          block = bdeGetSelectedBlock(diagram);
          explicitLink = bdeGetExplicitLink(diagram, block, 1, 'output');
          srcPortNumber = bdeGetLinkSourcePortNumber(explicitLink);


          
            srcPortNumber = 1
