### MCI_AUDIO_INIT Field - abLoadPath[LOAD_PATH]

abLoadPath[LOAD_PATH] (CHAR) If the digital signal processor (DSP) code must be loaded before the operation can be performed, the device driver sets the LOAD_CODE bit in ulFlags. In this case, the name of the DSP file to be loaded is specified in the abLoadPath field. Notice that the application must call AUDIO_LOAD before trying to perform Read or Write operations.

Keep a single copy of each DSP load module maintained and grouped together in a single subdirectory. This subdirectory can be referenced in the DOS APPEND command or the OS/2 DPATH CONFIG.SYS statement.

The maximum path length available for DSP code modules in abLoadPath is:

    LOAD_PATH    260    /* DOS and OS/2 length is 260 */
