I'm working on tool to allow you to easily change your Trackpoint settings on the Lenovo thinkpads. The little nipple. I'm writing it in C to help me learn the language more. I'm having a problem I can't quite put my paw on.
The code responsible for changing the setting is:
int set_nipple_speed(int speed) {
if (speed <= 0) {
printf("Invalid value %d speed must be greater than 0", speed);
return 1;
}
char command[100];
char * path = get_trackpoint_path();
sprintf(command, "echo %d | sudo tee %s/serio2/speed", speed, path);
return system(command);
}I'm getting:
tee: /sys/devices/platform/i8042/serio1: Is a directory
33
sh: 2: /serio2/speed: not foundOh and theres a function being called to get the base path to get to the trackpoint settings:
char *get_trackpoint_path() {
FILE *pipe_stream =
popen("find /sys/devices/platform/i8042 -name name | xargs grep -Fl "
"TrackPoint | sed 's/\\/input\\/input[0-9]*\\/name$//'",
"r");
char path[2048];
if (pipe_stream == NULL) {
printf("Failed to run command to find trackpoint path");
return NULL;
}
fgets(path, sizeof(path), pipe_stream);
pclose(pipe_stream);
char *path_ptr = path;
return path_ptr;
}Would anyone be willing to help me #debug this? I'm pretty new to C. Project is here #codinghelp
