Function

GLibstrcanon

Declaration [src] 

gchar*
g_strcanon (
  gchar* string,
  const gchar* valid_chars,
  gchar substitutor
)

Description [src]

For each character in string, if the character is not in valid_chars, replaces the character with substitutor.

Modifies string in place, and return string itself, not a copy. The return value is to allow nesting such as:

g_ascii_strup (g_strcanon (str, "abc", '?'))

In order to modify a copy, you may use g_strdup():

reformatted = g_strcanon (g_strdup (const_str), "abc", '?');
…
g_free (reformatted);
