The cvt package provides functions that convert data from foreign host to local host integer formats and back. These functions are designed to make use of a byte order signature that describes the byte order of the foreign host.
Reference material for this library is available in the reference manual page for cvt .
This chapter gives an high level view of how the library should be used.
The conversion library is a set of C functions. To use it, you will need to include the library header in your source code with a line like:
You will also need to link the conversion library into your executable program. Since the conversion headers and libraries are generally not installed in the normal search paths for headers and libraries, you will need to help the compiler find them at compile and link time. In this discussion, we will assume you have defined an environment variable DAQROOT to point to he NSCL DAQ installation directory (at the NSCL this will typically be in /usr/opt/daq/some-version where some-version is the version of the NSCLDAQ you are selecting.
Example 48-2. Compiling a C or C++ source file that includes cvt.h
gcc -c -I$DAQROOT/include myprogram.c or g++ -c -I$DAQROOT/include myprogram.cpp
