Syntax

[Visual Basic]

control.BassPluginStreamCreateFunc (

strPluginPathname as String,

strFuncName as String,

nType as enumBassPluginStreamCreateFuncs

) as enumErrorCodes

[C++]

short control.BassPluginStreamCreateFunc (

BSTR strPluginPathname,

BSTR strFuncName,

short nType

);

Parameter

Description

strPluginPathname

String containing the absolute or relative pathname of the BASS plugin. For example "Bass_AIX.dll".

If the string specifies a full path, the function searches only that path for the module.

If the string specifies a relative path or a module name without a path, the function uses the standard search strategy adopted by the LoadLibraryEx Windows API to find the module.

strFuncName

String containing the exact name of the function to import. For example "BASS_AIX_StreamCreateFile" or "BASS_AIX_StreamCreateURL".

nType

Type of function.
