16.6.1 Dl Objects
Dl objects, as returned by open() above, have the
following methods:
-
Free all resources, except the memory.
-
Return the pointer for the function named name, as a number, if
it exists in the referenced shared object, otherwise
None . This
is useful in code like:
>>> if a.sym('time'):
... a.call('time')
... else:
... time.time()
(Note that this function will return a non-zero number, as zero is the
NULL pointer)
call( |
name[, arg1[, arg2...]]) |
-
Call the function named name in the referenced shared object.
The arguments must be either Python integers, which will be
passed as is, Python strings, to which a pointer will be passed,
or
None , which will be passed as NULL. Note that
strings should only be passed to functions as const char*, as
Python will not like its string mutated.
There must be at most 10 arguments, and arguments not given will be
treated as None . The function's return value must be a C
long, which is a Python integer.
Release 2.5.2, documentation updated on 21st February, 2008.
