NAME
ne_strparam - HTTP extended parameter value encoding
SYNOPSIS
#include <ne_string.h>
-
char *ne_strparam(const char *charset, const char *lang, const char *value);
DESCRIPTION
The
ne_strparam
function can be used to encode an extended parameter value for an HTTP header, as defined in RFC 5987. The function takes as arguments the
value
to encode, using a given MIME
charset
character set, and
lang
language tag. The extended parameter encoding is used in HTTP protocol specifications to allow easily embedding special characters (such as quote marks, separators or non-ASCII) in header values.
In accordance with RFC 5987, the
charset
argument must be either
"UTF-8"
or
"IS0-8859-1", but the
lang
argument may be
NULL.
RETURN VALUE
The return value is either:
NULL
-
if the value parameter is a "regular parameter" and does not need extended encoding
non-NULL
-
the encoding of the input value as an extended parameter as a NUL-terminated, malloc-allocated string
HISTORY
ne_strparam
is available in neon 0.32.0 and later.
