This makes a difference between ibook and powerbook.
Yes, I'm planning to use this for sane default values of Option
"MacModel" when I get time, but feel free to beat me to it.
Is this program ok? It looks at the platform line from /proc/cpuinfo
file. I am not sure what is the best line to look for.
#include <stdio.h>
#include <string.h>
// or enum instead?
#define UNKNOWN 0
#define IBOOK 1
#define POWERBOOK_SINGLELINK 2
#define POWERBOOK_DUALLINK 3
int main (void){
int param = UNKNOWN;
FILE *f = fopen ("/proc/cpuinfo", "r");
#define MAX 100
char line[MAX];
if (f != NULL){
while (fgets (line, MAX, f)){
if (strncmp (line, "platform", strlen ("platform")) == 0){ //
found the line
if (strstr (line, "Book")) // to check on ibook computers
param = IBOOK;
else if (strstr (line, "Power"))
param = POWERBOOK_SINGLELINK;
// else: not apple computer, nothing to do
break;
}
}
}else
printf ("(WW) Cannot detect laptop DVI because /proc/cpuinfo not
readable. Please use the MacModel option in xorg.conf to configure it.\n");
printf ("%d\n", param);
return 0;
}
