Get the flags for a file
#include <sys/dcmd_blk.h> #define DCMD_FSYS_FILE_FLAGS __DIOTF(_DCMD_FSYS, 20, struct fs_fileflags)
Argument | Value |
---|---|
filedes | A file descriptor that you obtained by opening the device. |
dcmd | DCMD_FSYS_FILE_FLAGS |
dev_data_ptr | A pointer to a struct fs_fileflags (see below) |
n_bytes | sizeof(struct fs_fileflags) |
dev_info_ptr | NULL |
This command gets flags that indicate file attributes. The chattr utility is a front end for this command; for information about the flags, see its entry in the Utilities Reference.
None.
The fs_fileflags structure is defined as follows:
struct fs_fileflags { uint16_t mask[2]; uint16_t bits[2]; char basetype[16]; };
The members include:
struct fs_fileflags ff; memset(&ff, 0, sizeof ff); if((err = devctl(fd, DCMD_FSYS_FILE_FLAGS, &ff, sizeof ff, 0)) != EOK) { printf("fsys_file_flags=%s(%d)\n", strerror(err), err); } else { printf("fsys_file_flags=%#x:%#x\n", ff.bits[0], ff.bits[1]); }
