sds_catjson()

sds sds_catjson	(	sds	s,
		const char *	p,
		size_t	len
	)

Append to the sds string "s" a quoted json escaped string After the call, the modified sds string is no longer valid and all the references must be substituted with the new pointer returned by the call.

Parameters

s	sds string
p	string to append json escaped
len	length of the string to append

Returns

modified sds string

sds_catjson_plain()

sds sds_catjson_plain	(	sds	s,
		const char *	p,
		size_t	len
	)

Append to the sds string "s" a json escaped string After the call, the modified sds string is no longer valid and all the references must be substituted with the new pointer returned by the call.

Parameters

s	sds string
p	string to append json escaped
len	length of the string to append

Returns

modified sds string

sds_catjsonchar()

sds sds_catjsonchar	(	sds	s,
		const char	c
	)

Append to the sds string "s" an json escaped character After the call, the modified sds string is no longer valid and all the references must be substituted with the new pointer returned by the call.

Parameters

c	char to escape and append

Returns

modified sds string

sds_dirname()
