System::Call kernel32::GetPrivateProfileSectionNamesA

Hi,

I try to call 'kernel32::GetPrivateProfileSectionNamesA' with
'System::Call' to get all section names from an Inifile.

The API function returns a buffer with null-terminated strings.

I use the following code:

StrCpy $2 ${NSIS_MAX_STRLEN}
StrCpy $3 "Test.ini"
System::Call "kernel32::GetPrivateProfileSectionNamesA(t, i, t) i(.r1, r2, r3) .r4"

MessageBox MB_ICONEXCLAMATION|MB_OK "$1 $4"

$1 contains only the first section name. Is it possible to use something like shift on $1 to get the other parameters or does System::Call cut off itself the string at first nullchar.

Is there a way to use GetPrivateProfileSectionNamesA in NSIS or should I better use FileOpen, FileRead?

thx
