如何读取一个目录下的文件数和子目录内的文件书！

[yby123]

如题，求教给位前辈，能否给出一些函数或者方法。
谢谢了
是不是要定义一个全局变量，然后设定你每次循环读取的目录与子目录的名字
然后把数据相加？用ftw函数？

_findfirst and _findnext
MSND下吧
struct _finddata_t c_file;
intptr_t hFile;

// Find first .c file in current directory
if( (hFile = _findfirst( "*.c", &c_file )) == -1L )
printf( "No *.c files in current directory!\n" );
else
{
printf( "Listing of .c files\n\n" );
printf( "RDO HID SYS ARC FILE DATE %25c SIZE\n", ' ' );
printf( "--- --- --- --- ---- ---- %25c ----\n", ' ' );
do {
char buffer[30];
printf( ( c_file.attrib & _A_RDONLY ) ? " Y " : " N " );
printf( ( c_file.attrib & _A_HIDDEN ) ? " Y " : " N " );
printf( ( c_file.attrib & _A_SYSTEM ) ? " Y " : " N " );
printf( ( c_file.attrib & _A_ARCH ) ? " Y " : " N " );
ctime_s( buffer, _countof(buffer), &c_file.time_write );
printf( " %-12s %.24s %9ld\n",
c_file.name, buffer, c_file.size );
} while( _findnext( hFile, &c_file ) == 0 );
_findclose( hFile );
}

不是 我忘记说了 是linuxC sorry

1.用LINUX提供的API
2.调用一个shell命令，如 ls|wc -w就可统计文件数
