CallInstDLL

dllfile function_name

Calls a function named function_name inside a NSIS extension DLL, a plug-in. See the example plugin for how to make one. Extension DLLs can access the stack and variables. Note: To automatically extract and call plug-in DLLs, use a plug-in command instead of CallInstDLL.

Push "a parameter"
Push "another parameter"
CallInstDLL $INSTDIR\somedll.dll somefunction

For easier plug-in handling, use the new plug-in call syntax.

Command introduced with NSIS v1.7b
