.Bd -literal

.Ed
|
|
.Pp
|
|
The function
|
|
.Fn properties_read
|
|
reads
|
|
.Fa name = value
|
|
pairs from the file descriptor passed in
|
|
.Fa fd
|
|
and returns the head of a new property list, assuming that the
|
|
file's contents have been parsed properly, or NULL in case
|
|
of error.
|
|
.Pp
|
|
.Fn property_find
|
|
Returns the associated value string for the property named
|
|
.Fa name
|
|
if found, otherwise NULL. The value returned may be up to
|
|
.Dv PROPERTY_MAX_VALUE
|
|
bytes in length.
|
|
.Pp
|
|
.Fn properties_free
|
|
is used to free the structure returned by
|
|
.Fn properties_read
|
|
when it is no longer needed.
|
|
.Sh FILE FORMAT
|
|
Each property in the file is assumed to have the format of
|
|
.Fa name = value
|
|
where
|
|
.Fa name
|
|
is an alphanumeric string (and any punctuation not including the `=' character)
|
|
and
|
|
.Fa value
|
|
is an arbitary string of text terminated by a newline character. If newlines
|
|
are desired, the entire value should be enclosed in { } (curly-bracket)
|
|
characters. Any line beginning with a # or ; character is assumed to
|
|
be a comment and will be ignored.
