Description
The ipm_GetCapabilities( ) function returns the number of capabilities of the specified type (for example, coders) and details of each capability supported by an active HMP software license. The number of capabilities available may be greater than the number specified by the a_num input parameter, therefore the following rules apply:
•If a_num is zero and/or a_CapabilitiesArray[] is NULL, this function returns only the number of capabilities available; no capability detail is retrieved.
•If a_num is larger than the number of capabilities available (the return value),
a_CapabilitiesArray[] is filled with details of all capabilities and the remaining allocated memory is unused.
•If a_num is smaller than the number of capabilities available (the return value),
a_CapabilitiesArray[] is filled with details of a_num capabilities (that is, as many as will fit); details of the remaining capabilities are not retrieved.
Parameter | Description |
n_DeviceHandle | handle of the IP Media device |
a_CapType | capability type, for example CAPABILITY_CODERLIST |
a_num | the number of entries in the capability array |
a_CapabilitiesArray[] | the capability array |
a_usMode | operation mode |
| Set to EV_SYNC for synchronous execution |
