I am using mqx 3.5 , I wrote a code to count no. of files present in root directory wiith extension ".txt".
It is crashing while closing directory.I have attached the code also below .
char *arg[2];
DIR_STRUCT_PTR dir_ptr;
int result;
char_ptr path_ptr, mode_ptr;
int_32 error = 0;
int_32 return_code = SHELL_EXIT_SUCCESS;
char *buffer_file = NULL;
path_ptr ="*.txt";
mode_ptr = "m*";
arg[1] = path_ptr;
arg[2] = mode_ptr;
message.header.size = sizeof(sSoeFile);
fs_ptr = Shell_get_current_filesystem(arg);
if (fs_ptr == NULL)
{
printf("Error, file system not mounted\n");
return_code = SHELL_EXIT_ERROR;
}
else
{
buffer_file = _mem_alloc(FILE_MAXSIZE);
if (buffer_file && !error)
{
dir_ptr = _io_mfs_dir_open(fs_ptr, path_ptr, mode_ptr );
if (dir_ptr == NULL)
{
printf("File not found.\n");
}
else
{
while ((_io_is_fs_valid(fs_ptr)) && (len = _io_mfs_dir_read(dir_ptr, buffer_file, BUFFER_SIZE)) > 0)
totalfile++;
}
}
else
{
printf("Memory allocation Error\n");
}
}
_io_mfs_dir_close(dir_ptr);
