BASS_ATTRIB_DOWNLOADPROC attribute

The download callback function on an internet stream.

BASS_ChannelSetAttributeEx(
    DWORD handle,
    BASS_ATTRIB_DOWNLOADPROC,
    void *info,
    DWORD size
);

Parameters

handle	The channel handle.
info	A pointer to a DOWNLOADPROC callback function and user parameter. The user parameter is optional; if it is not included then the existing value will be kept.
size	The size of the info. This should be the size of one or two pointers, depending on whether a user parameter is included.

Remarks

This attribute can be used to change the DOWNLOADPROC callback function that was set in a BASS_StreamCreateURL call. The new callback function will only receive data that is subsequently downloaded, not any that has already been downloaded. Callbacks can be disabled by setting it to NULL.

This attribute can be set at any time, including within a DOWNLOADPROC function.

Platform-specific

For Java on Android, a BASS_ChannelSetAttributeDOWNLOADPROC function is provided to set this attribute, to be used instead of BASS_ChannelSetAttributeEx. It will not be possible to get the same value back from BASS_ChannelGetAttributeEx (as it will be converted to an internal wrapper form) except when it is NULL.

Example

Set a new download callback on a stream.

void *info[2] = { (void*)DownloadProc, user };
BASS_ChannelSetAttributeEx(stream, BASS_ATTRIB_DOWNLOADPROC, info, sizeof(info));

Disable download callbacks on a stream.

void *proc = NULL;
BASS_ChannelSetAttributeEx(stream, BASS_ATTRIB_DOWNLOADPROC, &proc, sizeof(proc));
