Declaration
gchar*
g_regex_replace (
const GRegex* regex,
const gchar* string,
gssize string_len,
gint start_position,
const gchar* replacement,
GRegexMatchFlags match_options,
GError** error
)
Description
Replaces all occurrences of the pattern in regex with the
replacement text. Backreferences of the form ‘\number’ or
‘\g
There are also escapes that changes the case of the following text:
- \l: Convert to lower case the next character
- \u: Convert to upper case the next character
- \L: Convert to lower case till \E
- \U: Convert to upper case till \E
- \E: End case modification
If you do not need to use backreferences use g_regex_replace_literal().
The replacement string must be UTF-8 encoded even if G_REGEX_RAW was
passed to g_regex_new(). If you want to use not UTF-8 encoded strings
you can use g_regex_replace_literal().
Setting start_position differs from just passing over a shortened
string and setting G_REGEX_MATCH_NOTBOL in the case of a pattern that
begins with any kind of lookbehind assertion, such as “\b”.
