从inotify联机帮助页：

   IN_CREATE         File/directory created in watched directory (*).

可以通过捕获此事件来完成。

再次从手册页：

  Limitations and caveats
       Inotify  monitoring  of  directories  is  not recursive: to monitor subdirectories under a directory, additional watches must be created.  This can take a significant
       amount time for large directory trees.

因此，您将需要自己执行递归部分。您可以从这里开始看一个例子。您还应该看看项目的通知工具

注释中要求的示例 ：它监视/tmp/inotify1＆/tmp/inotify2查找创建的新文件并显示事件

#include <stdio.h>
#include <stdlib.h>
#include <errno.h>
#include <unistd.h>
#include <sys/types.h>
#include <sys/inotify.h>

#define EVENT_SIZE  ( sizeof (struct inotify_event) )
#define BUF_LEN     ( 1024 * ( EVENT_SIZE + 16 ) )

int main( int argc, char **argv ) 
{
    int length, i = 0;
    int fd;
    int wd[2];
    char buffer[BUF_LEN];

    fd = inotify_init();

    if ( fd < 0 ) {
        perror( "inotify_init" );
    }

    wd[0] = inotify_add_watch( fd, "/tmp/inotify1", IN_CREATE);
    wd[1] = inotify_add_watch (fd, "/tmp/inotify2", IN_CREATE);

    while (1){
        struct inotify_event *event;

        length = read( fd, buffer, BUF_LEN );

        if ( length < 0 ) {
            perror( "read" );
        }

        event = ( struct inotify_event * ) &buffer[ i ];

        if ( event->len ) {
            if (event->wd == wd[0]) printf("%s\n", "In /tmp/inotify1: ");
            else printf("%s\n", "In /tmp/inotify2: ");
            if ( event->mask & IN_CREATE ) {
                if ( event->mask & IN_ISDIR ) {
                    printf( "The directory %s was created.\n", event->name );       
                }
                else {
                    printf( "The file %s was created.\n", event->name );
                }
            }
        }
    }
    ( void ) inotify_rm_watch( fd, wd[0] );
    ( void ) inotify_rm_watch( fd, wd[1]);
    ( void ) close( fd );

    exit( 0 );
}

测试运行：

shadyabhi@archlinux ~ $ ./a.out 
In /tmp/inotify1: 
The file abhijeet was created.
In /tmp/inotify2: 
The file rastogi was created.
