// Wrappers for C++ standard library (STL) types (std::string, etc.)
|
|
// This is also an example of how you may wrap your own similar types.
|
|
|
|
// Compatibility:
|
|
// - std::string support is only guaranteed to work from C++11.
|
|
// If you try to use it pre-C++11, please share your findings (w/ info about compiler/architecture)
|
|
|
|
// Changelog:
|
|
// - v0.10: Initial version. Added InputText() / InputTextMultiline() calls with std::string
