where are located daqmx C libraries (or API)??

Hi all,

i have just installed nidqamx 20.1 with online installer, and i need to find where C libraries (API funcion) are located. I need to use these libraries with external C compiler, not with labview, but i can find their location. The help says that lib files are located in

NI-DAQ\DAQmx ANSI C Dev\include

 but i do not have that directory after installation. Rather that the online help says that these libs are located in directory:

National Instruments\Shared\ExternalCompilerSupport\C\

 unfortunately i have non of those directory in my "national instrument" folder, i just have something similiar that is

C:\Program Files\National Instruments\Shared\mxef

 which contains some similiar libraries, but i don t know whic one i have to link to my project. Please give some ideas,

Kind Regards
