Functions Introduced:

A symbol instance may replace any text inside a note in the symbol definition that is enclose in back slash characters. The opaque data structure ProDtlvartext describes such a substitution. It describes the “prompt” string, that is, the string in the symbol definition which it is replacing, and the “value”, that is, the new text string.

The function ProDtlvartextAlloc() allocates and initializes a ProDtlvartext object. ProDtlvartextFree() frees the memory, and ProDtlvartextDataGet() unpacks the information in a ProDtlvartext.
