; MODULE NAME: EMM07_A.ASM ;
; ;
; FUNCTION NAME: get_EMM_version ;
; ;
; DESCRIPTION: This function returns the version number of the memory ;
; manager software. ;
; ;
; PASSED: &version: ;
; is a far pointer to the memory manager's version ;
; number. ;
; ;
; RETURNED: version: ;
; is the memory manager's version number in binary ;
; coded decimal (BCD) format. The upper four bits ;
; contain the integer digit of the version number. ;
; The lower four bits contain the fractional digit of ;
; version number. For example, version 4.0 is ;
; represented like this: ;
; 0100 0000 ;
; / \ ;
; 4 . 0 ;
; When checking for a version number, an application ;
; should check for a version number or greater. ;
; Vendors may use the fractional digit to indicate ;
; enhancements or corrections to their memory ;
; managers. Therefore, to allow for future versions ;
; of memory managers, an application shouldn't depend ;
; on an exact version number. ;
; ;
; RETURNED: status: ;
; is the status EMM returns from the call. All other ;
; returned results are valid only if the status ;
; returned is zero. Otherwise they are undefined. ;
; ;
; C USE CONVENTION: unsigned int status; ;
; unsigned int version; ;
; ;
; status = get_emm_version (&version); ;
