resampler_append_plugs()

static bool resampler_append_plugs ( void **  re, const retro_resampler_t **  backend, enum resampler_quality  quality, double  bw_ratio  )

static

resampler_append_plugs: : Resampler handle : Resampler backend that is about to be set. : Bandwidth ratio.

Initializes resampler driver based on queried CPU features.

Returns: true (1) if successfully initialized, otherwise false (0).
