This function is intended for use with vensim_get_vecvals. By filling up a vector of offsets you can speed the retrieval of multiple values.
Arguments
varname This is a full subscripted variable name that you want the offset for.
Returns
The offset of the variable name, or 0 if the variable name is not found or is not of the right type. Note that the offset returned is 1 greater than the offsets used internally by Vensim. The internal offsets are passed to external function.
Notes
It is a Vensim convention that time is always offset 1.
If you look at mdl.c you will notice that the offsets are 1 smaller than that returned by the function. This is because internally Vensim uses 0 based, not 1 based offsets. Do not adjust the offset returned since vensim_get_vecvals expects 1 based offsets.
