struct stat

The buffer of type struct stat used by the target and No value for GDBN is defined as follows:

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 */
};

The integral datatypes conform to the definitions given in the appropriate section (see Integral Datatypes, for details) so this structure is of size 64 bytes.

The values of several fields have a restricted meaning and/or range of values.

st_dev

A value of 0 represents a file, 1 the console.

st_ino

No valid meaning for the target. Transmitted unchanged.

st_mode

Valid mode bits are described in Constants. Any other bits have currently no meaning for the target.

st_uid

st_gid

st_rdev

No valid meaning for the target. Transmitted unchanged.

st_atime

st_mtime

st_ctime

These values have a host and file system dependent accuracy. Especially on Windows hosts, the file system may not support exact timing values.

The target gets a struct stat of the above representation and is responsible for coercing it to the target representation before continuing.

Note that due to size differences between the host, target, and protocol representations of struct stat members, these members could eventually get truncated on the target.
