| 11 | 08 Dec 08 SHL Add missing OS2_INCLUDED check
|
|---|
| 12 | 12 Jul 09 GKY Add xDosQueryAppType and xDoxAlloc... to allow FM/2 to load in high memory
|
|---|
| 13 | 26 Aug 11 GKY Add a low mem version of xDosAlloc* wrappers; move error checking into all the
|
|---|
| 14 | xDosAlloc* wrappers.
|
|---|
| 15 | 09 Aug 15 SHL Add xDosGetInfoBlocks
|
|---|
| 16 | 12 Aug 15 JBS Ticket #522: Ensure no "highmem-unsafe" functions are called directly
|
|---|
| 17 | 1) New functions have been added
|
|---|
| 18 | 2) Code for unsafe-but-not-yet-used-by-FM/2 functinos have been added in an
|
|---|
| 19 | "#if 0" block in wrappers.c for quick implementation should FM/2 start to use them.
|
|---|
| 20 | Among these. xDosOpenL and xWinUpper still need work. The rest are ready for use.
|
|---|
| 21 | 20 Aug 15 SHL Add xDos...MutexSem and xDos..EventSem wrappers
