glib 中的 g_file_test 问题

发布于 2024-10-02 06:51:55 字数 596 浏览 2 评论 0原文

我正在尝试学习 glib/gtk。我编写了一些代码来打印目录中的文件，如果它们是普通文件则分配“f”，如果它们是目录则分配“d”。问题在于如果。它总是获取错误值并将“f”附加到文件名。

#include <glib.h>
#include <glib/gstdio.h>
#include <glib/gprintf.h>

int main()
{
    GDir* home = NULL;
    GError* error = NULL;
    gchar* file = "a";

    home = g_dir_open("/home/stamp", 0, &error);
    while (file != NULL) 
    {
        file = g_dir_read_name(home);
        if (g_file_test(file, G_FILE_TEST_IS_DIR))
        {
            g_printf("%s: d\n", file);
        } else {
            g_printf("%s: f\n", file);
        }
    }
}

Im trying to learn glib/gtk. I wrote little code which prints files in directory and assigns "f" if they are normal files or "d" if they are directory. Problem is with if. It always gets false value and appends "f" to file name.

#include <glib.h>
#include <glib/gstdio.h>
#include <glib/gprintf.h>

int main()
{
    GDir* home = NULL;
    GError* error = NULL;
    gchar* file = "a";

    home = g_dir_open("/home/stamp", 0, &error);
    while (file != NULL) 
    {
        file = g_dir_read_name(home);
        if (g_file_test(file, G_FILE_TEST_IS_DIR))
        {
            g_printf("%s: d\n", file);
        } else {
            g_printf("%s: f\n", file);
        }
    }
}

g_dir_read_name 仅返回目录/文件名。您需要构建完整路径才能使用 g_file_test 进行测试。您可以使用 g_build_filename 来实现。

int main()
{
    GDir* home = NULL;
    GError* error = NULL;
    gchar* file = "a";

    home = g_dir_open("/home/stamp", 0, &error);
    while (file != NULL) 
    {
        file = g_dir_read_name(home);

        gchar* fileWithFullPath;
        fileWithFullPath = g_build_filename("/home/stamp", file, (gchar*)NULL);
        if (g_file_test(fileWithFullPath, G_FILE_TEST_IS_DIR))
        {
            g_printf("%s: d\n", file);
        }
        else
        {
            g_printf("%s: f\n", file);
        }
        g_free(fileWithFullPath);
    }
    g_dir_close( home );
}

g_dir_read_name returns just the directory/file name. You need to build full path in order to test it using g_file_test. You can use g_build_filename for that.

int main()
{
    GDir* home = NULL;
    GError* error = NULL;
    gchar* file = "a";

    home = g_dir_open("/home/stamp", 0, &error);
    while (file != NULL) 
    {
        file = g_dir_read_name(home);

        gchar* fileWithFullPath;
        fileWithFullPath = g_build_filename("/home/stamp", file, (gchar*)NULL);
        if (g_file_test(fileWithFullPath, G_FILE_TEST_IS_DIR))
        {
            g_printf("%s: d\n", file);
        }
        else
        {
            g_printf("%s: f\n", file);
        }
        g_free(fileWithFullPath);
    }
    g_dir_close( home );
}
