String to perform search and replacements on.

Maximum length of the string buffer.

String to search for.

String to replace the search string with.

Описание

Replaces a contained string iteratively.

Пометка

Consider using replace_string() instead.

Пометка

This ensures that no infinite replacements will take place by
intelligently moving to the next string position each iteration.

Возвращает

Number of replacements on success, otherwise 0.
