Constants

PA_CVOLUME_SNPRINT_MAX

The maximum length of strings returned by pa_cvolume_snprint. Please note that this value can change with any release without warning and without being considered API or ABI breakage. You should not use this definition anywhere where it might become part of an ABI.

PA_CVOLUME_SNPRINT_VERBOSE_MAX

The maximum length of strings returned by pa_cvolume_snprint_verbose. Please note that this value can change with any release without warning and without being considered API or ABI breakage. You should not use this definition anywhere where it might become part of an ABI.

PA_DECIBEL_MININFTY

This floor value is used as minus infinity when using pa_sw_volume_to_dB / pa_sw_volume_from_dB.

PA_SW_CVOLUME_SNPRINT_DB_MAX

The maximum length of strings returned by pa_sw_cvolume_snprint_dB. Please note that this value can change with any release without warning and without being considered API or ABI breakage. You should not use this definition anywhere where it might become part of an ABI.

PA_SW_VOLUME_SNPRINT_DB_MAX

The maximum length of strings returned by pa_sw_volume_snprint_dB. Please note that this value can change with any release without warning and without being considered API or ABI breakage. You should not use this definition anywhere where it might become part of an ABI.

PA_VOLUME_INVALID

Special ‘invalid’ volume

PA_VOLUME_MAX

Maximum valid volume we can store

PA_VOLUME_MUTED

Muted (minimal valid) volume (0%, -inf dB)

PA_VOLUME_NORM

Normal volume (100%, 0 dB)

PA_VOLUME_SNPRINT_MAX

The maximum length of strings returned by pa_volume_snprint. Please note that this value can change with any release without warning and without being considered API or ABI breakage. You should not use this definition anywhere where it might become part of an ABI.

PA_VOLUME_SNPRINT_VERBOSE_MAX

The maximum length of strings returned by pa_volume_snprint_verbose, as per the underlying C function. Please note that this value can change with any release without warning and without being considered API or ABI breakage. You should not use this definition anywhere where it might become part of an ABI.
