Detailed Description

The PVFS2 system interface provides functionality used for everyday interaction.

Both the PVFS2 kernel support and the PVFS2 ROMIO implementation build on this interface.

---

Typedef Documentation

typedef PVFS_id_gen_t PVFS_sys_op_id

Holds a non-blocking system interface operation handle.

---

Enumeration Type Documentation

enum PVFS_sys_setinfo_opt

Options supported by get_info() and set_info().

---

Function Documentation

PVFS_error PVFS_sys_dist_free (  PVFS_sys_dist *  dist  )

Free resources associated with this distribution.

PVFS_sys_dist* PVFS_sys_dist_lookup (  const char *  dist_identifier  )

Return the distribution associated with the given identifier, or null if none exists.

PVFS_error PVFS_sys_dist_setparam (  PVFS_sys_dist *  dist, const char *  param, void *  value )

Set the named distribution parameter with the given value.
