[ELanguage] ucw-src129 DL : 0: UC Library Extensions UnderC comes with a pocket implementation of the standard C++ libraries, which is a reasonably faithful subset. This documentation describes those UnderC functions and classes which are not part of the C++ standard. UC Library Builtin functions: Most of these are standard C functions, but there are a few unique to the UnderC system which give you runtime access to the compiler. You may evaluate expressions, execute commands, compile code, etc. * Expands the text in expr using the UnderC preprocessor, putting the result into buff. void uc_macro_subst(const char* expr, char* buff, int buffsize) * Executes a UC #-command, like #l or #help. uc_cmd() expects the name of the command, _without_ the hash, e.g. uc_cmd(\"l fred.cpp\") or uc_cmd(\"help\"). void uc_cmd(const char* cmd) * Evaluates any C++ expression or statement will return non-zero if unsuccessful.
