sf_pctdecode
============

Synopsis
--------

*#include <sfparse.h>*

.. function:: void sf_pctdecode(sf_vec *dest, const sf_vec *src)

    
    `sf_pctdecode` decodes percent-encoded string *src* and writes the
    result into *dest*.  *src* should be the pointer to
    :member:`sf_value.vec` of type :enum:`sf_type.SF_TYPE_DISPSTRING`
    produced by either `sf_parser_dict`, `sf_parser_list`,
    `sf_parser_inner_list`, `sf_parser_item`, or `sf_parser_param`,
    otherwise the behavior is undefined.
    
    :member:`dest->base <sf_vec.base>` must point to the buffer that
    has sufficient space to store the decoded byte string.  The memory
    areas pointed by :member:`dest->base <sf_vec.base>` and
    :member:`src->base <sf_vec.base>` must not overlap.
    
    This function sets the length of decoded byte string to
    :member:`dest->len <sf_vec.len>`.
