C++ (Cpp) read_int_file Examples

Example #1

File: main.c Project: smillaedler/rr

static void assert_prerequisites() {
	int aslr_val =
		read_int_file("/proc/sys/kernel/randomize_va_space");
	int ptrace_scope_val =
		read_int_file("/proc/sys/kernel/yama/ptrace_scope");
	if (aslr_val != 0) {
		fatal("ASLR not disabled; randomize is %d", aslr_val);
	}
	if (ptrace_scope_val > 0) {
		fatal("Can't write to process memory; ptrace_scope is %d",
		      ptrace_scope_val);
	}
}

Example #2

File: gpio.c Project: francois-berder/LetMeCreate

static int read_int_gpio_file(uint8_t gpio_pin, const char *file_name, uint8_t *value)
{
    char path[MAX_STR_LENGTH];
    uint32_t tmp;

    if (!create_gpio_path(path, gpio_pin, file_name))
        return -1;

    if (read_int_file(path, &tmp) < 0)
        return -1;

    *value = tmp;
    return 0;
}
