Description

The gpfs_direntx64_t structure contains the attributes of a GPFS directory entry.

Members

d_version

The version number of this structure.

d_reclen

The actual size of this structure including the null-terminated variable-length d_name field.

To allow some degree of forward compatibility, careful callers should use the d_reclen field for the size of the structure rather than the sizeof() function.

d_type

The type of directory.

d_ino

The directory inode number.

d_gen

The directory generation number.

d_flags

The directory flags.

d_name

Null-terminated variable-length name of the directory.
