sf_unescape
===========

Synopsis
--------

*#include <sfparse.h>*

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

    
    `sf_unescape` copies *src* to *dest* by removing escapes (``\``).
    *src* should be the pointer to :member:`sf_value.vec` of type
    :enum:`sf_type.SF_TYPE_STRING` 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 unescaped 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 unescaped string to
    :member:`dest->len <sf_vec.len>`.
