Calling C code in a JavaScript HTTP script

Question

Is it possible to call C functions in a JavaScript HTTP script? Something similar to "Evaluate C" step in TruClient. This is for LRE 2023R1.

Hi Antonio, 
 I see what you looking for. Many customers using VTS and the related lrvtc_xx api only for this purpose of handling data within Web http scripts. For this we don't have any wrappers or c-functions available that can call the lrd_xx DB functions inside a JS web script. 
 Since this will fall under customization, you may request to raise an enhancement for the same asking for a custom API 
 Thanks,

Hi Antonio, 
 For any HTTP script, you can either generate the steps in C or Javascript as the language but cannot use the functions interchangeably within same script. Compiler can only recognize 1 language at a time based on how code is generated. However programatically, there may be ways to call c-functions from with Javascript using some wrappers. If that works in any external JS compiler, it should work in VuGen too 
 Hope this answers your question. If anything specific around this, suggest to pls open a support incident with OT support and provide the sample script folder showing what you intend to do. We'd be glad to look into it further 
 
 Thanks,
