Returns values of static system variables.
Syntax: value = spQuerySysInfo (valueID)
Parameter: valueID – identifier of system variable to be queried.
|QSV_MAX_PATH_LENGTH||Maximum length, in bytes, of a path name.|
|QSV_MAX_TEXT_SESSIONS||Maximum number of text sessions.|
|QSV_MAX_PM_SESSIONS||Maximum number of PM sessions.|
|QSV_MAX_VDM_SESSIONS||Maximum number of DOS sessions.|
|QSV_BOOT_DRIVE||Drive from which the system was started (1 means drive A, 2 means drive B, and so on).|
|QSV_DYN_PRI_VARIATION||Dynamic priority variation flag (0 means absolute priority, 1means dynamic priority).|
|QSV_MAX_WAIT||Maximum wait in seconds.|
|QSV_MIN_SLICE||Minimum time slice in milliseconds.|
|QSV_MAX_SLICE||Maximum time slice in milliseconds.|
|QSV_PAGE_SIZE||Memory page size in bytes. This value is 4096 for the 80386 processor.|
|QSV_VERSION_MAJOR||Major version number.|
|QSV_VERSION_MINOR||Minor version number.|
|QSV_MS_COUNT||Value of a 32-bit, free-running millisecond counter. This value is zero when the system is started.|
|QSV_TIME_LOW||Low-order 32 bits of the time in seconds since January 1, 1970 at 0:00:00.|
|QSV_TIME_HIGH||High-order 32 bits of the time in seconds since January 1, 1970 at 0:00:00.|
|QSV_TOTPHYSMEM||Total number of bytes of physical memory in the system.|
|QSV_TOTRESMEM||Total number of bytes of resident memory in the system.|
|QSV_TOTAVAILMEM||Maximum number of bytes of memory that can be allocated by all processes in the system. This number is advisory and is not guaranteed, since system conditions change constantly.|
|QSV_MAXPRMEM||Maximum number of bytes of memory that this process can allocate in its private arena. This number is advisory and is not guaranteed, since system conditions change constantly.|
|QSV_MAXSHMEM||Maximum number of bytes of memory that a process can allocate in the shared arena. This number is advisory and is not guaranteed, since system conditions change constantly.|
|QSV_TIMER_INTERVAL||Timer interval in tenths of a millisecond.|
|QSV_MAX_COMP_LENGTH||Maximum length, in bytes, of one component in a path name.|
|QSV_FOREGROUND_FS_SESSION||Session ID of the current foreground full-screen session. Note that this only applies to full-screen sessions. The Presentation Manager session (which displays Viowindowed, PM, and windowed DOS Sessions) is full-screen session ID 1.|
|QSV_FOREGROUND_PROCESS||Process ID of the current foreground process.|
Returns: Value of system variable.
