// -*- mode: cpp; mode: fold -*- // Description /*{{{*/ /* ###################################################################### Version Test - Simple program to run through a file and comare versions. Each version is compared and the result is checked against an expected result in the file. The format of the file is a b Res Where Res is -1, 1, 0. dpkg -D=1 --compare-versions a "<" b can be used to determine what Res should be. # at the start of the line is a comment and blank lines are skipped The runner will also call dpkg --compare-versions to check if APT and dpkg have (still) the same idea. ##################################################################### */ /*}}}*/ #include <apt-pkg/macros.h> #include <apt-pkg/error.h> #include <apt-pkg/version.h> #include <apt-pkg/debversion.h> #include <apt-pkg/fileutl.h> #include <iostream> #include <fstream> #include <stdlib.h> #include <unistd.h> #include <sys/types.h> #include <sys/wait.h> using namespace std; bool callDPkg(const char *val, const char *ref, const char &op) { pid_t Process = ExecFork(); if (Process == 0) { const char * args[6]; args[0] = "/usr/bin/dpkg"; args[1] = "--compare-versions"; args[2] = val; args[3] = (op == 1) ?
