* GetComputerObjectNameA (SECUR32.@)
*
* Get the local computer's name using the format specified.
*
* PARAMS
* NameFormat [I] The format for the name.
* lpNameBuffer [O] Pointer to buffer to receive the name.
* nSize [I/O] Size in characters of buffer.
*
* RETURNS
* TRUE If the name was written to lpNameBuffer.
* FALSE If the name couldn't be written.
*
* NOTES
* If lpNameBuffer is NULL, then the size of the buffer needed to hold the
* name will be returned in *nSize.
*
* nSize returns the number of characters written when lpNameBuffer is not
* NULL or the size of the buffer needed to hold the name when the buffer
* is too short or lpNameBuffer is NULL.
*
* It the buffer is too short, ERROR_INSUFFICIENT_BUFFER error will be set.
