Is there any way to check in Linux C if a file is a text file, e.g. UTF or ASCII? In bash we have the function file. Is there any equivalent in C?
如果文件是文本文件，例如UTF或ASCII，是否有办法检查Linux C ?在bash中，我们有函数文件。在C中是否有等价的?
EDIT: This is my function to validate a text file in C. I use popen, but it does not work fine. Sometimes I have a error in pclose. What would need editing in the code?
编辑:这是我在c中验证一个文本文件的函数。我使用popen，但是它不工作。有时在pclose中有一个错误。需要在代码中编辑什么?
int check_file(char *path)
{
FILE *file_type;
char command[] = "/usr/bin/file";
char command_to_execute[512];
char check[512];
int correct = 0;
sprintf(command_to_execute,"%s %s",command,path);
file_type = popen(command_to_execute,"r");
if(file_type == NULL)
{
return correct;
}
fgets(check,512,file_type);
char *pointer;
pointer = strstr(check,"ASCII");
if(pointer != NULL)
correct = 1;
pointer = strstr(check,"UTF");
if(pointer != NULL)
correct = 1;
pclose(file_type);
return correct;
}

file is a program (not a bash function); you could read the file and check for non-ascii characters. If you find any output false and stop processing, if you reach the end of the file output true.
文件是一个程序(不是bash函数);您可以读取文件并检查非ascii字符。如果您发现任何输出错误和停止处理，如果您到达文件输出的末端为真。
