我正在尝试编写 ac 代码来扫描整个目录以查找以 .wor 结尾的文件，打开每个文件并从中提取某些信息。
到目前为止，我的代码已成功打开该目录中的所有文件，并扫描它们以查找目标词。有没有办法让我修改代码，使其只扫描以 .wor 结尾的文件？我尝试了通配符“*.wor”，但它只是给我一个错误，说符号 * 和 .wor 无法识别。
非常感谢你的帮助！
（顺便说一句，我最后添加的计数器也无法工作，我尝试使用整数“c”在每次读取文件时递增，并显示最后读取的文件总数。它只是给出我现在是 0。）

这是我的代码：

    #include <stdio.h>
    #include <string.h>
    #include <stdlib.h>
    #include <sys/types.h>
    #include <dirent.h>

    #include <errno.h>

char *device;
char *testprog;
char *software;
char *dutboardid;
char *corlbox;
int i=0;

struct dirent* in_file;
int c = 0;


    FILE * ft = fopen ( "WorkOrderInfo.csv", "w" ) ;    /* Open file to write to*/
    if ( ft == NULL )
    {
           puts ( "Cannot open target file" ) ;
           exit( 1 ) ;
    }

    fprintf (ft, "Work Order,Customer,Device,Test_Prog,Software,DUT_board_id,Corl box\n");

您可以手动检查每个文件名是否以.wor如下方式结尾：

size_t len = strlen(in_file->d_name);
if (len >= 4 && memcmp(in_file->d_name + len - 4, ".wor", 4) == 0)
{
    // The filename ends in ".wor" (case-sensitive).  Note that this also
    // accepts the file whose entire name is ".wor".
}

或者，您可以改为使用该glob(3)函数来获取与特定通配符匹配的文件名列表：

// Error checking omitted for expository purposes
glob_t globbuf;
glob("/home/iselabs/dwang/pinscale/workorder/practice/*.wor", 0, NULL, &globbuf);

for (size_t i = 0; i < globbuf.gl_pathc; i++)
{
    char *filename = globbuf.gl_pathv[i];
    // Process filename...
}

globfree(&globbuf);
