如何使用readdir实现文件搜索

#<span>include <stdio.h></span>
#<span>include <stdlib.h></span>
#<span>include <dirent.h></span>
#<span>include <string.h></span>

void search_files(<span>const char *path)</span> {
    DIR *dir;
    <span>struct dirent *entry;</span>

    dir = opendir(path);
    if (dir == NULL) {
        perror("opendir");
        return;
    }

    while ((entry = readdir(dir)) != NULL) {
        if (strcmp(entry->d_name, ".") == 0 || strcmp(entry->d_name, "..") == 0) {
            continue;
        }

        char full_path[1024];
        snprintf(full_path, sizeof(full_path), "%s/%s", path, entry->d_name);

        if (entry->d_type == DT_DIR) {
            search_files(full_path);
        } else {
            printf("%s\n", full_path);
        }
    }

    closedir(dir);
}

int main(<span>int argc, char *argv[])</span> {
    if (argc < 2) {
        printf("Usage: %s <directory_path>\n", argv[0]);
        return 1;
    }

    search_files(argv[1]);

    return 0;
}

gcc file_search.c -o file_search
./file_search /path/to/search
