Question of using "ZeroMemory" in IVF8.0

[Zhanghong_T_]

In CVF6.6, I have a simple code:

use dfwbase
real*8,allocatable::aa(:)
allocate(aa(1000000))
call ZeroMemory(loc(aa), 1000000*sizeof(real*8))

END

But in IVF8.0, it can not run correctly. Who can tell me where it is wrong?

Thanks!

That compiles? Maybe, if you don't have IMPLICIT NONE.

In CVF/IF, SIZEOF() cannot take a type-name as an argument. You must use an actualvariable instead:

call ZeroMemory(loc(aa), sizeof(aa))

Compiler interprets your actual code as a variable named REAL multiplied by 8.

Thank you for your reply! I have modified just like what you have said, but it still can not work!

In fact, in IVF8.0, I have replaced the use dfwbase with use kernel32(it is wrong when I don't replace this code).

Could you elaborate on "don't work"?

[Zhanghong_T_]

When I use dfwbase in IVF8.0,

the compiler display the following error when linking:

unresolved external symbol ZEROMEMORY@8

When I replaced it with use kernel32 and debug it(run to the last line), it display:

Unhandled exception in test.exe: 0xC0000005: Access Violation when read 0x00000000.

the display is Chinese, I have translated it to English.

Anyone help me?
