Replace a substring of a string with another string.

Replace a substring of a string with another string.

Name	Type	Default	Description
Return	char*		Pointer to the entry string. The entry string will be changed. There must be sufficient memory available.
str	char*	-	String, in which the replacement(s) are to be made.
search	char*	-	Character string to be replaced since v3.2.3 R2600, 08.08.2011 The search string may be a regular expression. Use prefix "regexp:" to mark a search string as a regular expression. since v3.3 R4000, 4. Jul 2013 With prefix "pcre:" a new machine for regular expressions is used. We recomment using this machine! Since v3.4 R9000 and CS5 only PCRE is used for regulare expressions. The prefix regexp: is still allowed but will use PCRE too. Only CS4 still uses the old GNU compatible implementation.
replace	char*	-	Character string to be entered
doAll	int	1	0 : Only replace the first occurrence 1 : Replace all occurrences
startPos	int	0	Start position for replacings, only valid for regular expressions.
compile_options	int	0	Additional options while compiling regular expression, see here
study_options	int	0	Additional options while studying compiled regular expression, see here
exec_options	int	0	Additional options while executing regular expression, see here

strcpy (str, "Matthias");

strreplace (str, "tt", "t") returns "Mathias"
strreplace (str, "a", "aAa") returns "MaAathiaAas"

Find all 3-digit substrings enclosed by letters and swap this letters.

Regular expression working with "pcre:" but not with "regexp:"

int main ()

    char		str [512];

    strcpy (str, "abc11188888#defgh11177777#hijklmn11166666#opqäöü55555#qwertzu11144444#XYZ");

    wlog ("", "POST	: '%s'\n", str);

    return 0;
}
