);
Parameters

Pointer to a string that contains the identifier.
[in] psDefUsage
Pointer to a CRYPT_PROVIDER_REGDEFUSAGE structure that contains callback information.
Return value
The return value is TRUE if the function succeeds; FALSE if the function fails. If the function fails, call the GetLastError function to determine the reason for failure.
