rstr_len


Description:

[ CCode ( cname = "g_strrstr_len" ) ]
public unowned string? rstr_len (ssize_t haystack_len, string needle)

Searches the string haystack for the last occurrence of the string needle, limiting the length of the search to haystack_len.

Example: Search for the last occurrence of a substring:

public static int main (string[] args) {
string str = "This is hardly rocket science, this is quantum physics!";
unowned string? pos = str.rstr_len (str.length, "science");
// Output: ``science, this is quantum physics!``
print ("%s\n", pos);
return 0;
}

valac --pkg glib-2.0 string.rstr_len.vala

Parameters:

haystack_len

the maximum length of haystack in bytes. A length of `-1` can be used to mean "search the entire string", like [ func@GLib.strrstr]

needle

the string to search for

haystack

a string to search in

Returns:

a pointer to the found occurrence, or `NULL` if not found
