Functions
void	replace_chr (char *s, char c1, char c2)
	Replace all occurrences of narrow character c1 with narrow character c2 in s, using case-sensitive search. If c2 is '\0' then all matches to c1 are effectively removed from the string.
void	replace_chri (char *s, char c1, char c2)
	Replace all occurrences of narrow character c1 with narrow character c2 in s, using case-insensitive search. If c2 is '\0' then all matches to c1 are effectively removed from the string.
static void	_append_range (char **buffer, const char *start, const char *end)
	Helper function to append a range of characters to a string that may need to be resized to accommodate the range of characters.
char *	replace_str (const char *s, const char *str1, const char *str2)
	Replace all occurrences of narrow string str1 with narrow string str2 in s, using case-sensitive search, returning a new string.
char *	replace_stri (const char *s, const char *str1, const char *str2)
	Replace all occurrences of narrow string str1 with narrow string str2 in s, using case-insensitive search, returning a new string.

Function Documentation

_append_range()

static void _append_range ( char **  buffer, const char *  start, const char *  end  )

static

Helper function to append a range of characters to a string that may need to be resized to accommodate the range of characters.

Parameters

buffer	Pointer to a pointer to a character string. This will contain the pointer to the updated string on return.
start	Pointer to first character of range to copy.
end	Pointer to one after last character of range to copy. Must be greater than or equal to start and must point into the same string.

replace_chr()

void replace_chr	(	char *	s,
		char	c1,
		char	c2
	)

Replace all occurrences of narrow character c1 with narrow character c2 in s, using case-sensitive search. If c2 is '\0' then all matches to c1 are effectively removed from the string.

Parameters

s	String to modify
c1	Character to replace
c2	Character to replace with

replace_chri()

void replace_chri	(	char *	s,
		char	c1,
		char	c2
	)

Replace all occurrences of narrow character c1 with narrow character c2 in s, using case-insensitive search. If c2 is '\0' then all matches to c1 are effectively removed from the string.

Parameters

s	String to modify
c1	Character to replace
c2	Character to replace with

Definition at line 51 of file replace.c.

replace_str()

char * replace_str	(	const char *	s,
		const char *	str1,
		const char *	str2
	)

Replace all occurrences of narrow string str1 with narrow string str2 in s, using case-sensitive search, returning a new string.

Parameters

s	String to modify
str1	String to replace
str2	String to replace with (can be an empty string to remove str1).

Returns

Returns a new string containing the modifications. The string must be released using free()

replace_stri()

char * replace_stri	(	const char *	s,
		const char *	str1,
		const char *	str2
	)

Replace all occurrences of narrow string str1 with narrow string str2 in s, using case-insensitive search, returning a new string.

Parameters

s	String to modify
str1	String to replace
str2	String to replace with (can be an empty string to remove str1).

Returns

Returns a new string containing the modifications. The string must be released using free()
