The last element of path must be NULL.
Load a suitable version of an Intel® Threading Building Blocks (Intel® TBB) dynamic library from one of the specified directories.
The method searches for a library in directories specified in the path array. When a library is found, it is loaded and its interface version (as returned by TBB_runtime_interface_version()) is checked. If the version does not meet the requirements specified by min_ver and max_ver, the library is unloaded. The search continues in the next specified path, until a suitable version of the Intel TBB library is found or the array of paths ends with NULL. It is recommended to use default values for min_ver and max_ver.
For security reasons, avoid using relative directory names such as current ("."), parent ("..") or any other relative directory (like "lib") when searching for a library. Use only absolute directory names (as shown in the example above); if necessary, construct absolute names at run time. Neglecting these rules may cause your program to execute 3-rd party malicious code. (See http://www.microsoft.com/technet/security/advisory/2269637.mspx for details.)

ec_bad_call - this runtime_loader instance has already been used to load a library.
ec_bad_lib - A library was found but it appears invalid.
ec_bad_arg - min_ver and/or max_ver is negative or zero, or min_ver > max_ver.
ec_bad_ver - unsuitable version has already been loaded by another instance.
ec_no_lib - No suitable version was found.
