GLib.ascii_strncasecmp
Description: Reference for GLib.ascii_strncasecmp

### Function

# GLibascii_strncasecmp

#### Declaration [src]

    gint
    g_ascii_strncasecmp (
      const gchar* s1,
      const gchar* s2,
      gsize n
    )

#### Description [src]

Compare `s1` and `s2`, ignoring the case of ASCII characters and any characters after the first `n` in each string. If either string is less than `n` bytes long, comparison will stop at the first nul byte encountered.

Unlike the BSD `strncasecmp()` function, this only recognizes standard ASCII letters and ignores the locale, treating all non-ASCII characters as if they are not letters.

The same warning as in `g_ascii_strcasecmp()` applies: Use this function only on strings known to be in encodings where bytes corresponding to ASCII letters always represent themselves.

#### Parameters

`s1`

  Type: `const gchar*`

  String to compare with `s2`.

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

`s2`

  Type: `const gchar*`

  String to compare with `s1`.

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

`n`

  Type: `gsize`

  Number of characters to compare.

#### Return value

Type: `gint`

0 if the strings match, a negative value if `s1` < `s2`, or a positive value if `s1` > `s2`.
