How do I start the values as in the example C++ code?
struct Gains{ uint8_t totalGain = FORCE_FEEDBACK_MAXGAIN; uint8_t constantGain = FORCE_FEEDBACK_MAXGAIN; uint8_t rampGain = FORCE_FEEDBACK_MAXGAIN; uint8_t squareGain = FORCE_FEEDBACK_MAXGAIN; uint8_t sineGain = FORCE_FEEDBACK_MAXGAIN; uint8_t triangleGain = FORCE_FEEDBACK_MAXGAIN; uint8_t sawtoothdownGain = FORCE_FEEDBACK_MAXGAIN; uint8_t sawtoothupGain = FORCE_FEEDBACK_MAXGAIN; uint8_t springGain = FORCE_FEEDBACK_MAXGAIN; uint8_t damperGain = FORCE_FEEDBACK_MAXGAIN; uint8_t inertiaGain = FORCE_FEEDBACK_MAXGAIN; uint8_t frictionGain = FORCE_FEEDBACK_MAXGAIN; uint8_t customGain = FORCE_FEEDBACK_MAXGAIN; }; struct EffectParams{ int32_t springMaxPosition = 0; int32_t springPosition = 0; int32_t damperMaxVelocity = 0; int32_t damperVelocity = 0; int32_t inertiaMaxAcceleration = 0; int32_t inertiaAcceleration = 0; int32_t frictionMaxPositionChange = 0; int32_t frictionPositionChange = 0; }; //force feedback gain struct Gains* m_gains; //force feedback effect params struct EffectParams* m_effect_params;
If you're writing C++, just do it.
If you're not, you can't.
How do I start values in C?

Like I said: you don't. If you strongly believe you need that feature, you will have to write your code in C++. It's ultimately as simple as that.
Nor is it ever called "start". The C++ feature you're trying to use is called a default value. It's used by the constructor, for those members of the struct the user didn't supply their own initializer values, for . C simply doesn't have that entire set of features.
