Function

GLibutf8_collate

Declaration

gint
g_utf8_collate (
  const gchar* str1,
  const gchar* str2
)

Description

Compares two strings for ordering using the linguistically correct rules for the [current locale][setlocale]. When sorting a large number of strings, it will be significantly faster to obtain collation keys with g_utf8_collate_key() and compare the keys with strcmp() when sorting instead of sorting the original strings.

If the two strings are not comparable due to being in different collation sequences, the result is undefined. This can happen if the strings are in different language scripts, for example.

Parameters

str1 const gchar*
 

A UTF-8 encoded string.

 The data is owned by the caller of the function.
 The value is a NUL terminated UTF-8 string.
str2 const gchar*
 

A UTF-8 encoded string.

 The data is owned by the caller of the function.
 The value is a NUL terminated UTF-8 string.

Return value

Returns: gint
 

< 0 if str1 compares before str2, 0 if they compare equal, > 0 if str1 compares after str2.
