acmFormatDetails
The acmFormatDetails function queries the ACM for format details for a specific waveform-audio
format tag.
MMRESULT acmFormatDetails(
HACMDRIVER had,
|
| LPACMFORMATDETAILS pafd,
|
| DWORD fdwDetails
|
| );
|
|
Parameters
had
Handle of the ACM driver to query for waveform-audio format details for a
format tag. If this parameter is NULL, the ACM uses the details from the first
suitable ACM driver.
pafd
Address of an ACMFORMATDETAILS structure to contain the format details for the given format tag.
fdwDetails
Flags for getting the waveform-audio format tag details. The following values
are defined:
ACM_FORMATDETAILSF_FORMAT
A WAVEFORMATEX structure pointed to by the pwfx member of the ACMFORMATDETAILS structure was given and the remaining details should be returned. The dwFormatTag member of the ACMFORMATDETAILS structure must be initialized to the same format tag as pwfx specifies. This query type can be used to get a string description of an
arbitrary format structure. If an application specifies an ACM driver handle for had, details on the format 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_FORMATDETAILSF_INDEX
A format index for the format tag was given in the dwFormatIndex member of the ACMFORMATDETAILS structure. The format details will be returned in the structure defined by pafd. The index ranges from zero to one less than the cStandardFormats member returned in the ACMFORMATTAGDETAILS structure for a format tag. An application must specify a driver handle for had when retrieving format details with this flag. For information about which
members should be initialized before calling this function, see the ACMFORMATDETAILS structure.
Return Values
Returns zero if successful or an error otherwise. Possible error values
include the following:
ACMERR_NOTPOSSIBLE
| The details requested are not available.
| MMSYSERR_INVALFLAG
| At least one flag is invalid.
| MMSYSERR_INVALHANDLE
| The specified handle is invalid.
| MMSYSERR_INVALPARAM
| At least one parameter is invalid.
