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.

Deprecated since:	2.70
Use `g_pattern_spec_match()` instead.

Parameters

`pspec`	`GPatternSpec`
	A `GPatternSpec`.
	The data is owned by the caller of the function.
`string_length`	`guint`
	The length of `string` (in bytes, i.e. strlen(), not g_utf8_strlen())
`string`	`const gchar*`
	The UTF-8 encoded string to match.
	The data is owned by the caller of the function.
	The string is a NUL terminated UTF-8 string.
`string_reversed`	`const gchar*`
	The reverse of `string` or `NULL`.
	The argument can be `NULL`.
	The data is owned by the caller of the function.
	The string is a NUL terminated UTF-8 string.

Return value

Returns:	`gboolean`
	`TRUE` if `string` matches `pspec`.
