In fact, nothing there seems to be right. FWIW, here's a tweaked version of that program that gives you whatever information it can get, and warns you about what it can't. <mike /* * FreeBSD CPU Information 0.2 * --------------------------- * Simple program to display the total RAM, and CPU information. * Compile: cc -o cpuinfo cpuinfo.c * --------------------------- * Omachonu Ogali <oogali@intranova.net> */ #include <stdio.h> #include <stdlib.h> #include <string.h> #include <unistd.h> #include <sys/types.h> #include <sys/sysctl.h> extern int errno; int main(void) { int len, numcpu, cpuspeed, totalmem, usermem; char cpuarch[64], cpumodel[64]; printf("FreeBSD CPU Information\n"); printf("Version 0.2\n"); printf("http://tribune.intranova.net\nhttp://www.mired.org/\n\n"); len = sizeof(cpuarch); if (sysctlbyname("hw.machine_arch", &cpuarch, &len, NULL, NULL) == -1) { perror("sysctlbyname(hw.machine_arch)"); cpuarch[0] = 0; } len = sizeof(cpumodel); if (sysctlbyname("hw.model", &cpumodel, &len, NULL, NULL) == -1) { perror("sysctlbyname(hw.model)"); cpumodel[0] = 0; } len = sizeof(cpuspeed); if (sysctlbyname("machdep.tsc_freq", &cpuspeed, &len, NULL, NULL) == -1) { perror("sysctlbyname(machdep.tsc_freq)"); cpuspeed = -1; } len = sizeof(numcpu); if (sysctlbyname("hw.ncpu", &numcpu, &len, NULL, NULL) == -1) { perror("sysctlbyname(hw.ncpu)"); numcpu = -1; } len = sizeof(totalmem); if (sysctlbyname("hw.physmem", &totalmem, &len, NULL, NULL) == -1) { perror("sysctlbyname(hw.physmem)"); totalmem = -1; } len = sizeof(usermem); if (sysctlbyname("hw.usermem", &usermem, &len, NULL, NULL) == -1) { perror("sysctlbyname(hw.usermem)"); usermem = -1; } if (cpuarch[0]) printf("Architecture:\t%s\n", cpuarch); if (numcpu > 0) printf("Number of CPUs:\t%d\n", numcpu); if (cpumodel[0]) printf("CPU Model:\t%s\n", cpumodel); if (cpuspeed > 0) printf("CPU Speed:\t%dMHz\n", cpuspeed / 1000000); if (totalmem > 0) printf("Total Memory:\t%dMB\n", (totalmem - 1048576) / 1048576); if (usermem > 0) printf("User Memory:\t%dMB\n", (usermem - 1048576) / 1048576); printf("\n"); return 0; } -- Mike Meyer <mwm@mired.org> http://www.mired.org/home/mwm/ Independent WWW/Unix/FreeBSD consultant, email for more information.
