const char* spvm_version_string = SPVM_NATIVE_VERSION_STRING;Macro Functions
spvm_warn
#define spvm_warn(format, ...)Prints the formatted message format to stderr with a new line.
format must be the char* type.
Examples:
spvm_warn("Hello");
spvm_warn("Hello %s%d", "Foo", 3);spvm_warnf
#define spvm_warnf(stream, format, ...)Prints the formatted message format to the stream stream with a new line.
format must be the char* type.
stream must be the FILE type.
Examples:
spvm_warnf(env->spvm_stderr(env, stack), "Hello");
