Here's a version that compiles and runs. I've added a couple of extra
capabilities too:
- it passes the environment variables to its child process, so it runs
wine with execve() rather than execlp()
- the abandon() function reports errors, showing what the program
was doing, the error code that was returned and its meaning.
- Wine runs its command line arguments for added flexibility, so
testw winefile
runs Wine's Windows Explorer workalike. You'll see that it fiddles
with the argument list, substituting "wine" for the first argument
and adding a after the last argument null to terminate the array.
Both are necessary.
=========================testw.c============================
#include <sys/io.h>
#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <errno.h>
void abandon(char *text)
{
fprintf(stderr,
"Error: %s: err %d,%s\n",
text, errno, strerror(errno));
exit(1);
}
int main(int argc, char *argv[], char *envp[])
{
char **args;
int i;
args = (char**)malloc((argc + 1) * sizeof(char*));
if (!args)
abandon("malloc() failed");
for (i = 1; i < argc; i++)
args[i] = argv[i];
args[0] = "wine";
args[i] = 0;
ioperm(0,0x3ff,1); /* Allows access to all ports: poss. dangerous */
setuid(geteuid()); /* set effective uid */
if (execve("/usr/bin/wine", args, envp) == -1)
abandon("Failed to run wine");
free(args);
return 0;
}
=====================end of testw.c=========================
