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
