Hello List, I discovered that functions that are supposed to be defined in setupapi.h and cfgmgr32.h (CM_ and SetupDi family functions) are sometimes not defined in the headers that mingw ships. They *are* defined in the ones that are part of the Windows related SDKs provided by Microsoft. Is there a particular reason they are not contained? I found that the corresponding strings are in the .a files corresponding to the libraries. Kind regards Noel -- Noel Kuntze IT security consultant GPG Key ID: 0x0739AD6C Fingerprint: 3524 93BE B5F7 8E63 1372 AF2D F54E E40B 0739 AD6C -------------- next part -------------- A non-text attachment was scrubbed...
