00023 ======================== Contenido ========================
00024 Prototipos para primitivas basicas para tarjetas
00025 SoundBlaster definidas en SB.C.
00026 
00027 Si DSP_GET_DOUBLE_RATE esta definido, se declara la
00028 funcion sb_DSP_tc2dsr() que utiliza numeros en coma
00029 flotante.
00030 ....................
00031 Basic primitives for SB cards. Code is in SB.C.
00032 
00033 If DSP_GET_DOUBLE_RATE is defined, the function
00034 sb_DSP_tc2dsr() is declared. This function uses floating
00035 point numbers.
