Setting Up Eclipse for C++ Development (in Windows)



I'm not sure what the correct area/forum to post developer questions is but hopefully someone can point me in the right direction. If you can help me now, here's my problem....

My task is to take C code that was designed and previously compiled and run on the Solaris platform, and do what is necessary to make it compile and run on Windows. I'm using MinGW as my solution. I have it all set up and running but I ran into a few compile errors. The main error that I've been looking to resolve has to do with a "truncate" function that's being used to truncate a string. The error looks something like this:

       error: 'truncate' was not declared in this scope.<br><br>

This code previously worked on Solaris.

My question is, do you know what I should be using to perform String truncations in this version of the C compiler? Or is there a C library reference manual that I can view online to see what's available to me when using MinGW?

You really should use the mailing list to ask such questions.

Regarding online documentation resources, then the only one that is strictly relevant is MSDN; for a standard MinGW installation, the Visual Studio 6.0 Runtime Library Reference is probably the most appropriate:

(later versions are also supported, but VS-6.0 is the best fit for the standard MSVCRT.DLL, which is used as default by MinGW).

You may also wish to refer to the Windows API reference material, (but do watch out for version compatibility pitfalls):
