Function
GLibpattern_match
Declaration
gboolean
g_pattern_match (
GPatternSpec* pspec,
guint string_length,
const gchar* string,
const gchar* string_reversed
)
Description
Matches a string against a compiled pattern. Passing the correct
length of the string given is mandatory. The reversed string can be
omitted by passing NULL, this is more efficient if the reversed
version of the string to be matched is not at hand, as
g_pattern_match() will only construct it if the compiled pattern
requires reverse matches.
Note that, if the user code will (possibly) match a string against a multitude of patterns containing wildcards, chances are high that some patterns will require a reversed string. In this case, it’s more efficient to provide the reversed string to avoid multiple constructions thereof in the various calls to g_pattern_match().
Note also that the reverse of a UTF-8 encoded string can in general
not be obtained by g_strreverse(). This works only if the string
does not contain any multibyte characters. GLib offers the
g_utf8_strreverse() function to reverse UTF-8 encoded strings.
