SYNOPSIS
#include <ppath/ppath.h>
int
ppath_copydel_bool(prop_object_t, prop_object_t *, const ppath_t *);
int
ppath_copyset_bool(prop_object_t, prop_object_t *, const ppath_t *,
bool);
int
ppath_set_bool(prop_object_t, const ppath_t *, bool);
int
ppath_get_bool(prop_object_t, const ppath_t *, bool *);
int
ppath_delete_bool(prop_object_t, const ppath_t *);
DESCRIPTION
The ppath_bool routines read, write, or delete boolean values in a prop‐
erty list by path.
FUNCTIONS
ppath_bool provides these functions for manipulating boolean values in a
property list by the values' paths:
ppath_copydel_bool(prop_object_t o, prop_object_t *op, const ppath_t *p)
Create a copy of the property list o at *op. Delete from the copy
the prop_bool_t named by p.
If *op is NULL, ppath_copydel_bool() creates a shallow copy of o
at *op. If *op is not NULL, ppath_copydel_bool() expects for *op
to be an existing shallow copy of o.
For the purposes of ppath_copydel_bool(), *op is a shallow copy of
property list o if equal properties at equal paths are shared
between the two. Before ppath_copydel_bool() modifies a property
shared by *op and o, it creates a private copy of the property for
*op.
ppath_copyset_bool(prop_object_t o, prop_object_t *op, const ppath_t *p,
bool v)
Create a copy of the property list o at *op. In the copy, replace
with v the prop_bool_t named by p.
If *op is NULL, ppath_copyset_bool() creates a shallow copy of o
at *op. If *op is not NULL, ppath_copyset_bool() expects for *op
to be an existing shallow copy of o.
For the purposes of ppath_copyset_bool(), *op is a shallow copy of
property list o if equal properties at equal paths are shared
between the two. Before ppath_copydel_bool() modifies a property
shared by *op and o, it creates a private copy of the property for
*op.
ppath_set_bool(prop_object_t o, const ppath_t *p, bool v)
Replace with v the prop_bool_t in o named by p.
ppath_get_bool(prop_object_t o, const ppath_t *p, bool *vp)
Retrieve the prop_bool_t named by p from o, and write it to *vp.
ppath_delete_bool(prop_object_t o, const ppath_t *p)
Delete the prop_bool_t named by p from o. ppath_delete_bool()
decreases by one the deleted boolean value's reference count.
RETURN VALUES
ppath_bool routines return 0 on success, and non-zero on error.
ERRORS
[EFTYPE] A ppath_bool operation returns EFTYPE when the object
named by the path is not a prop_bool_t.
[ENOENT] ppath_bool routines return ENOENT if the path p does
not exist in o.
[ENOMEM] ppath_set_bool(), and ppath_copyset_bool() return
ENOMEM if there was insufficient memory to complete
the operation.
