acmFilterTagDetailsW function (msacm.h)
The acmFilterTagDetails function queries the ACM for details about a specific waveform-audio filter tag.
MMRESULT ACMAPI acmFilterTagDetailsW( HACMDRIVER had, LPACMFILTERTAGDETAILSW paftd, DWORD fdwDetails );
Handle to the ACM driver to query for waveform-audio filter tag details. If this parameter is NULL, the ACM uses the details from the first suitable ACM driver. An application must specify a valid HACMDRIVER or HACMDRIVERID identifier when using the ACM_FILTERTAGDETAILSF_INDEX query type. Driver identifiers for disabled drivers are not allowed.
Pointer to the ACMFILTERTAGDETAILS structure that is to receive the filter tag details.
Flags for getting the details. The following values are defined.
|ACM_FILTERTAGDETAILSF_FILTERTAG[ACMFILTERTAGDETAILS](./nf-msacm-acmfiltertagdetails.md) structure. The filter tag details will be returned in the structure pointed to by paftd. If an application specifies an ACM driver handle for had, details on the filter tag will be returned for that driver. If an application specifies NULL for had, the ACM finds the first acceptable driver to return the details.|
|ACM_FILTERTAGDETAILSF_INDEX[ACMDRIVERDETAILS](./nf-msacm-acmdriverdetails.md) structure for an ACM driver. An application must specify a driver handle for had when retrieving filter tag details with this flag.|
|ACM_FILTERTAGDETAILSF_LARGESTSIZE||Details on the filter tag with the largest filter size, in bytes, are to be returned. The dwFilterTag member must either be WAVE_FILTER_UNKNOWN or the filter tag to find the largest size for. If an application specifies an ACM driver handle for had, details on the largest filter tag will be returned for that driver. If an application specifies NULL for had, the ACM finds an acceptable driver with the largest filter tag requested to return the details.|
Returns zero if successful or an error otherwise. Possible error values include the following.
||The details requested are not available.|
||At least one flag is invalid.|
||The specified handle is invalid.|
||At least one parameter is invalid.|
The msacm.h header defines ACMFILTERTAGDETAILS as an alias which automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. Mixing usage of the encoding-neutral alias with code that not encoding-neutral can lead to mismatches that result in compilation or runtime errors.
