The RTW TLC Function Library

3-29

Note: By convention, start parameter names with a capital letter since the

Name identifier of the Parameter record is promoted into the parent block

scope. It is not mandatory that you do so, however, the Target Language

Compiler will exit if you attempt this assignment:

%assign kp = LibBlockParameter(kp, "", "", 0)

The Target Language Compiler exits because it does not know if the first kp is

the block identifier

kp or a local variable kp. One way to avoid the confusion is

to qualify which

kp you are assigning. A valid assignment is:

%assign block.kp = LibBlockParameter(kp, "", "", 0)

Avoid the confusion and stick to the convention by renaming the variable Kp in

the TLC file

%assign kp = LibBlockParameter(Kp, "", "", 0)

LibBlockOutportLocation(ucv, lcv, sigIdx)

The behavior of this function is similar to LibBlockOutputSignal, except it

returns the appropriate reference to a block outport signal. For an example,

see

outport.tlc.

LibCacheNonFiniteAssignment(assignment)

This function should be called from inside BlockTypeSetup to cache

assignments that need to be placed in the registration function because of

nonfinite initialization. That is, the

rtInfs, rtNaNs, and rtMinusInfs

parameters are initialized to zero until the registration function is called,

re-initializing them to their appropriate value. Each call to this function

appends your buffer to the existing cache buffer.
