| The buffer of type <code>struct stat</code> used by the target and <span class="sc">gdb</span> |
| is defined as follows: |
| |
| <pre class="smallexample"> struct stat { |
| unsigned int st_dev; /* device */ |
| unsigned int st_ino; /* inode */ |
| mode_t st_mode; /* protection */ |
| unsigned int st_nlink; /* number of hard links */ |
| unsigned int st_uid; /* user ID of owner */ |
| unsigned int st_gid; /* group ID of owner */ |
| unsigned int st_rdev; /* device type (if inode device) */ |
| unsigned long st_size; /* total size, in bytes */ |
| unsigned long st_blksize; /* blocksize for filesystem I/O */ |
| unsigned long st_blocks; /* number of blocks allocated */ |
| time_t st_atime; /* time of last access */ |
| time_t st_mtime; /* time of last modification */ |
| time_t st_ctime; /* time of last change */ |
| }; |
| </pre> |
| <p>The integral datatypes conform to the definitions given in the |
| appropriate section (see <a href="Integral-Datatypes.html#Integral-Datatypes">Integral Datatypes</a>, for details) so this |
| structure is of size 64 bytes. |
| |
| <p>The values of several fields have a restricted meaning and/or |
| range of values. |
| |
| <dl> |
| <dt><code>st_dev</code><dd>A value of 0 represents a file, 1 the console. |
| |
| <br><dt><code>st_ino</code><dd>No valid meaning for the target. Transmitted unchanged. |
| |
| <br><dt><code>st_mode</code><dd>Valid mode bits are described in <a href="Constants.html#Constants">Constants</a>. Any other |
| bits have currently no meaning for the target. |
| |
| <br><dt><code>st_uid</code><dt><code>st_gid</code><dt><code>st_rdev</code><dd>No valid meaning for the target. Transmitted unchanged. |
| |
| <br><dt><code>st_atime</code><dt><code>st_mtime</code><dt><code>st_ctime</code><dd>These values have a host and file system dependent |
| accuracy. Especially on Windows hosts, the file system may not |
| support exact timing values. |
| </dl> |
| |
| <p>The target gets a <code>struct stat</code> of the above representation and is |
| responsible for coercing it to the target representation before |
| continuing. |
| |
| <p>Note that due to size differences between the host, target, and protocol |
| representations of <code>struct stat</code> members, these members could eventually |
| get truncated on the target. |
