Interface Functions

There is a growing library of user interface functions which control various aspects of Xic for use in scripts.

Functions that manipulate objects in the database use a coordinate system based in microns (1 micron usually equals 1000 database units). All coordinates are real values.

There are two levels of run-time error reporting. For serious errors, a message is emitted to the controlling terminal, and the script terminates. Most interface functions will generate this type of error only in response to bad arguments, meaning usually arguments of the wrong type. Less serious errors simply cause the function to return, returning a value that indicates that the operation was unsuccessful. Many of the functions return 1 if successful, or 0 if not successful. In some cases where a string is normally returned, a null string return indicates an error occurred. It is up to the user to test the return values for success or failure.

When the documentation specifies that a null string value is acceptable as a function argument, the value zero can be passed instead of a string variable. The token NULL, which is predefined as 0, can be used equivalently.

The tables below list the collections of interface functions presently available, by category and sub-category. Most of these functions return a value. In the descriptions, if a value is returned, the type, in parentheses, is indicated ahead of the function name.
