[Patryk Kubiak]

Function vfprintf must be implemented according to the POSIX standard: http://www.cplusplus.com/reference/cstdio/vfprintf/

Functions to use:

oC_ErrorCode_t   oC_KPrint_VPrintf           ( char * outBuffer , oC_UInt_t Size , oC_IoFlags_t IoFlags , const char * Format , va_list ArgumentList );
oC_ErrorCode_t       oC_VirtualFileSystem_fwrite        ( oC_File_t File , void * Buffer , uint32_t * Size );
