Methods Documentation

static change_file_namespace(fileno: int, ns1: str, ns2: str) → None

Change file number from ns1 to ns2

close(self: psi4.core.IO, unit: int, keep: int) → None

Close unit. If keep == 0, will remove the file, else keep it

exists(self: psi4.core.IO, unit: int) → bool

Check if the unit exists.

static get_default_namespace() → str

Get the default namespace (for PREFIX.NAMESPACE.UNIT file numbering)

getpid(self: psi4.core.IO) → str

Lookup process id

open(self: psi4.core.IO, unit: int, status: int) → None

Open unit. Status can be PSIO_OPEN_OLD (if existing file is to be opened) or PSIO_OPEN_NEW if new file should be open

open_check(self: psi4.core.IO, unit: int) → int

Return 1 if unit is open

rehash(self: psi4.core.IO, unit: int) → None

Sync up the object to the file on disk by closing and opening the file, if necessary

static set_default_namespace(ns: str) → None

Set the current namespace (for PREFIX.NAMESPACE.UNIT file numbering)

set_pid(self: psi4.core.IO, pid: str) → None

Set process id

static shared_object() → psi4.core.IO

Return the global shared object

state(self: psi4.core.IO) → int

Return 1 if PSIO library is activated

tocclean(self: psi4.core.IO, unit: int, key: str) → None

Delete all TOC entries after the given key. If a blank key is given, the entire TOC will be wiped

tocentry_exists(self: psi4.core.IO, arg0: int, arg1: str) → bool

Checks the TOC to see if a particular keyword exists there or not

tocprint(self: psi4.core.IO, arg0: int) → None

Print the table of contents for the given unit

tocscan(self: psi4.core.IO, arg0: int, arg1: str) → psi4.core.psio_entry

Seek string in binary file. This export is only good for catching None, as returned success object not exported.

tocwrite(self: psi4.core.IO, arg0: int) → None

Write the table of contents for passed file number
