The datatype for the a_CapabilitiesArray[] parameter is a union, IPM_CAPABILITIES, which is
defined as follows:
typedef struct ipm_capabilities_tag
{
unsigned int version;
union
{
IPM_CODER_INFO Coder;
// Future types here.
};
}IPM_CAPABILITIES;
In this union, the IPM_CODER_INFO data structure provides coder details such as coder type,
frame size, number of frames per packet, VAD enable/disable information, and payload-related
information.
The datatype for the a_CapType parameter is eCAPABILITY_TYPE, an enumeration that is
defined as follows:
enum eCAPABILTIY_TYPE
{
CAPABILITY_CODERLIST;
}
The ipm_GetCapabilities( ) function is supported in synchronous mode only. If asynchronous
mode (a_usMode = EV_ASYNC) is specified, an error is generated.
Cautions
None.
Errors

to return one of the following errors:
EIPM_BADPARM
Invalid parameter
EIPM_INTERNAL
Internal error
EIPM_INV_MODE

EIPM_INV_STATE
