Calling a C function with a varargs argument dynamically

Question

I am programming in C against a third party library (in HP/Mercury Loadrunner) that allows a varargs-style variable size argument list for one of it\'s functions. I want to

Answer 1

I know this is an old thread, but I just ran across it. The proper way to handle variable length submit form data in LoadRunner is to use a web_custom_request(). You build the name|value pair structure for the variable length of the arguments as a string and pass it in as a part of the function.

Record the one call as a web_custom_request() and the structure of the argument string for the name|value pairs will become obvious. Simply use any C string handling functions you wish to construct the string in question and include it as a part of the argument list for the web_custom_request().
