Steps to Reproduce

(1) The cfile is :

#define _POSIX_C_SOURCE 199309L // 用于启用 clock_gettime 函数

#include <stdio.h>
#include <stdlib.h>
#include <time.h>

int clock_time_get(clockid_t clock_id) {
    struct timespec tp;

    if (clock_gettime(clock_id, &tp) == 0) {
        printf("Successfully get the clock time.\n");
        printf("seconds: %ld\n", tp.tv_sec);
        printf("nano seconds: %ld\n", tp.tv_nsec);
    } else {
        perror("Failed to get the clock time.\n");
        return 1;
    }

    return 0;
}

int clock_time_getyq5TE7BLv8 (){
    clockid_t clock_id = CLOCK_PROCESS_CPUTIME_ID;
    return clock_time_get(clock_id);
}

int main() {
    clock_time_getyq5TE7BLv8 ();
}

(2)compile the c file into wasm: ./wasi-sdk-16.0/bin/clang --target=wasm32-unkown-wasi --sysroot=./wasi-sdk-16.0/share/wasi-sysroot clock2.c -o clock2.wasm
(3)exeute clock.wasm
wasmtime run clock2.wasm

Expected Results

Using gcc clock2.c -o clock2 and ./clock2 to execute get the following result:

Successfully get the clock time.
seconds: 0
nano seconds: 6283516

And wamr, wasmedge,wasmer also print the above message.

Actual Results

wasmtime prints:

Failed to get the clock time.
: Bad file descriptor

I'm not sure whether this is a bug. Maybe this is related to https://github.com/bytecodealliance/wasmtime/issues/7419
Sorry for bothering you. Thanks a lot !

@orangeC23 Can you please perform some investigation of your own into these issues before filing them? You are filing more issues than any other contributor, in a manner which appears to be the result of some automated system, and as far as I can tell, all of these issues have trivial answers which would only require you to examine a small amount of code.

We appreciate that @bjorn3 and @alexcrichton and others have taken a look at these, but it isn't very fair for you to consume their time and attention if you aren't showing that you are putting time and attention into these issues yourself.
