Eina_UStrbuf

Type for a string buffer.

Function Documentation

Eina_Bool eina_ustrbuf_append	(	Eina_UStrbuf *	buf,
		const Eina_Unicode *	str
	)

Append a string to a buffer, reallocating as necessary.

Since :: 2.3

Parameters:

[in]	buf	The string buffer to append to.
[in]	str	The string to append.

Returns:: EINA_TRUE on success, EINA_FALSE on failure.

Remarks:: This function appends str to buf. It computes the length of str, so is slightly slower than eina_ustrbuf_append_length(). If the length is known beforehand, consider using that variant. If buf can't append it, EINA_FALSE is returned, otherwise EINA_TRUE is returned.

See also:: eina_ustrbuf_append(); eina_ustrbuf_append_length()

Eina_Bool eina_ustrbuf_append_char	(	Eina_UStrbuf *	buf,
		Eina_Unicode	c
	)

Append a character to a string buffer, reallocating as necessary.

Since :: 2.3

Parameters:

[in]	buf	The string buffer to append to.
[in]	c	The char to append.

Returns:: EINA_TRUE on success, EINA_FALSE on failure.

Remarks:: This function inserts c to buf. If it can not insert it, EINA_FALSE is returned, otherwise EINA_TRUE is returned.

Eina_Bool eina_ustrbuf_append_escaped	(	Eina_UStrbuf *	buf,
		const Eina_Unicode *	str
	)

Append an escaped string to a buffer, reallocating as necessary.

Parameters:

buf	The string buffer to append to.
str	The string to append.

Returns:: EINA_TRUE on success, EINA_FALSE on failure.

Since :: 2.3

This function appends the escaped string str to buf. If str can not be appended, EINA_FALSE is returned, otherwise, EINA_TRUE is returned.

Eina_Bool eina_ustrbuf_append_length	(	Eina_UStrbuf *	buf,
		const Eina_Unicode *	str,
		size_t	length
	)

Append a string of exact length to a buffer, reallocating as necessary.

Since :: 2.3

Parameters:

[in]	buf	The string buffer to append to.
[in]	str	The string to append.
[in]	length	The exact length to use.

Returns:: EINA_TRUE on success, EINA_FALSE on failure.

Remarks:: This function appends str to buf. str must be of size at most length. It is slightly faster than eina_ustrbuf_append() as it does not compute the size of str. It is useful when dealing with strings of known size, such as eina_strngshare. If buf can't append it, EINA_FALSE is returned, otherwise EINA_TRUE is returned.

Eina_Bool eina_ustrbuf_append_n	(	Eina_UStrbuf *	buf,
		const Eina_Unicode *	str,
		size_t	maxlen
	)

Since :: 2.3

Parameters:

[in]	buf	The string buffer to append to.
[in]	str	The string to append.
[in]	maxlen	The maximum number of characters to append.

Returns:: EINA_TRUE on success, EINA_FALSE on failure.

Remarks:: This function appends at most maxlen characters of str to buf. It can't appends more than the length of str. It computes the length of str, so is slightly slower than eina_ustrbuf_append_length(). If the length is known beforehand, consider using that variant (maxlen should then be checked so that it is greater than the size of str). If str can not be appended, EINA_FALSE is returned, otherwise, EINA_TRUE is returned.
