Overview of modeling C code (C code)
In addition to the standard modeling techniques in Modeler, you can use the supplied C Profile package to record information that is specific to C.
The C Profile package contains Stereotypes and Tag Definitions required for modeling C code in the model. Through the Tag Definitions in the C profile, you can model information such as array specs, CV qualifiers and indirection.
If you reverse engineer C code to a model that does not contain the C profile, the Reverser creates a C Profile in the Model; however, the C profile it creates may contain only the Stereotypes and Tag Definitions required for the code you reverse engineered, and each Stereotype and Tag Definition of the C Profile package will not include a description of its purpose:
If the Reverser has created a C profile in your Model and you want to update it so that it is complete and includes the Stereotype and Tag Definition descriptions, see Overview of modeling C code (C code)
If you want to add a complete and documented C profile to a Model that does not contain the C Profile package, see Adding the C profile package to a model (C code)
Warning If you want to add additional Tag Definitions to items in the Model, do not do so through the supplied C Profile package. If you add Tag Definitions to the supplied Stereotypes, they may be unlinked when reverse engineering code. In addition, if you import the C Profile package again or upgrade Modeler, the C Profile package will be overwritten.
