void seGetLibseVersion(int ** Version)
Description:
Parameters:
Return Value: ERR_OK
int seGetMemSize(int DevID, DWORD * pSize)
Description:
Parameters:
Return Value: ERR_OK
int seGetLastUsableByte(int DevID, DWORD * pLastByte)
Description:
Parameters:
Return Value: ERR_OK
Memory size is only checked when calling seRegisterDevice(), seSetDisplayMode() or
seSetInit(). Afterwards, the memory size is stored and made available through seGet-
MemSize().
Retrieves the LIBSE library version for non-x86 platforms. The return pointer in
parameter Version is valid if the function return value is ERR_OK.
Version
ERR_FAILED - unable to complete operation. Probably on x86 platform where
LIBSE is not used.
This routine returns the amount of installed video memory. The memory size is
determined by reading the status of MD6 and MD7. *pSize will be set to either
80000h (512 KB) or 200000h (2 MB).
DevID
pSize
Calculates the offset of the last byte in the display buffer which can be used by appli-
cations. Locations following LastByte are reserved for system use. Items such as the
half frame buffer, hardware cursor and ink layer will be located in memory from
GetLastUsableByte() + 1 to the end of memory.
It is assumed that the registers will have been initialized before calling seGetLastUs-
ableByte(). Factors such as the half frame buffer and hardware cursor / ink layer
being enabled dynamically alter the amount of display buffer available to an appli-
cation. Call seGetLastUsableByte() any time the true end of usable memory is
required.
DevID
pLastByte
display buffer
- pointer to an int to store LIBSE version code
- no problems encountered, version code is valid
- registered device ID
- pointer to a DWORD to receive the size
- the operation completed successfully
- registered device ID
- pointer to a DWORD to receive the offset to the last usable byte of
- operation completed with no problems
