Every C source file that calls ODBC functions must include a platform-specific ODBC header file. Each platform-specific header file includes the main ODBC header file odbc.h, which defines all the functions, data types, and constant definitions required to write an ODBC program.
To include the ODBC header file in a C source file
Add an include line referencing the appropriate platform-specific header file to your source file. The lines to use are as follows:
|Operating system||Include line|
|Windows Mobile||#include "ntodbc.h"|
Add the directory containing the header file to the include path for your compiler.
Both the platform-specific header files and odbc.h are installed in the SDK\Include subdirectory of your SQL Anywhere installation directory.
When building ODBC applications for Unix, you might have to define the macro "UNIX" for 32-bit applications or "UNIX64" for 64-bit applications in order to obtain the correct data alignment and sizes. This step is not required if you are using one of the following supported compilers:
