RIL functions can be asynchronous or synchronous. Most of the RIL functions are asynchronous. For both asynchronous and synchronous RIL functions, an immediate asynchronous returned result, HRESULT, indicates success or failure of the function call.

For asynchronous functions, positive HRESULT values indicate success and are used as command identifications for matching the asynchronous callback. The asynchronous result callback returns the final result in a buffer. Valid command identifications are in the range 0x00000001 to 0x7fffffff. Zero is not a valid return value for asynchronous calls. Negative HRESULT values indicate an error. HRESULT error values of E_XXX are defined in winerror.h file. HRESULT error values of RIL_E_XXX are defined in Ril.h.

For synchronous functions, an HRESULT value of S_OK indicates success. An asynchronous result callback is not called. If a synchronous RIL function needs a final result, a pointer to a data structure is passed in the RIL function and the final result is put in the data structure. For synchronous functions, HRESULT values of E_XXX indicate an error. Errors are defined in winerror.h file.

The following table shows the RIL functions with a description of the purpose of each.
