--------------------
|
||||
01g,08aug12,l_z remove HWMEM_MAX_ALLOC. (WIND00364661)
|
||||
01f,09dec09,h_k reverted the hwMemAlloc prototype for LP64.
|
||||
01e,05nov09,h_k mapped hwMemAlloc() to calloc.
|
||||
01d,23jun09,jc0 fix WIND00170079, move hwMemShow() from hwMemLib.c to
|
||||
vxbShow.c
|
||||
01c,16jun09,x_s restriction hwMemFree() for small footprint
|
||||
01b,23feb09,h_k updated for LP64 support.
