ESL has an API that allows you to manipulate ESL string variables in C DLL routines. You must include ESLLIB.H in your source code to provide access to this API.
When using any of the functions prototyped in ESLLIB.H, you must link using ESLLIB.LIB. The following table lists the string manipulation commands in the ESL API:
