dlclose(3) Library Functions Manual dlclose(3)
NAME
dlclose - Close a dlopen() object
SYNOPSIS
#include <dlfcn.h>
int dlclose(void *handle)
PARAMETERS
A pointer to a global symbol object that is returned from a call to dlopen().
DESCRIPTION
The dlclose function is used to inform the system that the object referenced by a handle returned from a previous dlopen() invocation is no
longer needed by the application.
The use of dlclose() reflects a statement of intent on the part of the process, but does not create any requirements on the dynamic library
loader, such as removal of the code or symbols referenced by handle. Once an object has been closed using dlclose(), an application should
assume that its symbols are no longer available to dlsym(). All objects loaded automatically as a result of invoking dlopen() on the refer-
enced object are also closed.
The dlclose function deallocates the address space for the library corresponding to handle. The results are undefined if any user function
continues to call a symbol resolved in the address space of a library that has since been deallocated by dlclose.
The dlclose operation will not remove an object to which references have been relocated, until or unless all such references are removed.
For instance, an object that had been loaded with a dlopen() operation specifying the RTLD_GLOBAL flag might provide a target for dynamic
relocations performed in the processing of other objects - in such environments, an application may assume that no relocation, once made,
will be undone or remade unless the object requiring the relocation has itself been removed.
RETURN VALUE
If the referenced object was successfully closed, dlclose() returns 0. If the object could not be closed or if handle does not refer to an
open object, dlclose() returns a non-zero value. More detailed diagnostic information will be available through dlerror().
ERRORS
No errors are defined.
NOTES
The dlopen and dlclose routines might dynamically change the resolution of certain symbols referenced by a program or its shared library
dependencies. The dlopen routine might resolve symbols that were previously unresolved, and dlclose might cause resolved symbols to become
unresolved or to be reresolved to a different symbol definition.
A portable application will employ a handle returned from a dlopen() invocation only within a given scope bracketed by the dlopen() and
dlclose() operations. The dynamic library loader is free to use reference counting or other techniques such that multiple calls to
dlopen() referencing the same object may return the same object for handle. The dynamic library loader is also free to re-use a handle. For
these reasons, the value of a handle must be treated as an opaque object by the application, used only in calls to dlsym() and dlclose().
