DaqBIOS Command API
The DaqBIOS Command API is a direct copy of DaqBIOS commands to the IOM. Every DaqBIOS
command has its equivalent in the PowerDNA (PDNALib) library.
Any code using the PowerDNA Library must include the file, PDNA.h, which itself includes all
necessary additional header files.
2.1 Pre-defined Types and Error Codes
2.1.1 Pre-defined Types
These types are defined for use within the library.
DAQLIB is omitted from this document for the sake of readability. Under Microsoft Windows, it is used
for functions that are exported from the DAQLib dll for the user.
#define DAQLIB __declspec(dllexport) __stdcall
The following types keep the API call format similar across wide range of operating systems.
