LJM_AUTO_IPS_FILE is an LJM configuration that describes the absolute or relative file path of the LJM auto IPs file.

To read, pass LJM_AUTO_IPS_FILE to LJM_ReadLibraryConfigStringS to get a string containing the file path.

To write, pass LJM_AUTO_IPS_FILE and string containing a file path to LJM_WriteLibraryConfigStringS, or use LJM_LoadConfigurationFile.

The constant LJM_AUTO_IPS_FILE can be used interchangeably with the string "LJM_AUTO_IPS_FILE".
