Return Value: ERR_OK
void seGetHalVersion(const char ** pVersion, const char ** pStatus,
const char **pStatusRevision)
Description:
Parameters:
Return Value: None
Example:
void seGetLibseVersion(int ** Version)
Description:
Parameters:
Return Value: ERR_OK
int seGetMemSize(int DevID, DWORD * pSize)
Description:
seGetId() will disable hardware suspend on x86 platforms, and will enable the host in-
terface (register [1Bh]) on all platforms.
This document was written for HAL version “1.04”, so any later versions should be a
superset of the functions described here.
For the S1D13505 the return values are currently:
ID_S1D13505_REV0
ID_UNKNOWN
Other HAL libraries will return their respective controller IDs upon detection of
their controller.
ERR_UNKNOWN_DEVICE - returned when pID returns ID_UNKNOWN.
Retrieves the HAL library version. The return pointers are all to ASCII strings. A
typical return would be: *pVersion == “1.01” (HAL version 1.01),*pStatus == “B”
(The 'B' is the beta designator), *pStatusRevision == “5”. The programmer need
only create pointers of const char type to pass as parameters (see Example below).
pVersion
pStatus
pStatusRevision - pointer to string of HAL statusRevision
const char *pVersion, *pStatus, *pStatusRevision;
seGetHalVersion( &pVersion, &pStatus, &pStatusRevision);
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).
- operation completed with no problems
(The HAL was unable to identify the display controller).
- pointer to string of HAL version code
- pointer to string of HAL status code (NULL is release)
- pointer to an int to store LIBSE version code
- no problems encountered, version code is valid
