# krb5_vwrap_error_message - Add a prefix to a different error code’s message using a va_list.

void `krb5_vwrap_error_message`(krb5_context ctx, krb5_error_code old_code, krb5_error_code code, const char * fmt, va_list args)

param: | [in] ctx - Library context [in] old_code - Previous error code [in] code - Error code [in] fmt - Format string for error message prefix [in] args - List of vprintf(3) style arguments

This function is similar to `krb5_wrap_error_message()` , but uses a va_list instead of variadic arguments.
