sfparse_parser_param
====================

Synopsis
--------

*#include <sfparse.h>*

.. function:: int sfparse_parser_param(sfparse_parser *sfp, sfparse_vec *dest_key, sfparse_value *dest_value)

    
    `sfparse_parser_param` reads a parameter.  If this function returns
    0, it stores parameter key and value in *dest_key* and *dest_value*
    respectively, if they are not NULL.
    
    This function does no effort to find duplicated keys.  Same key may
    be reported more than once.
    
    Caller should keep calling this function until it returns negative
    error code.  If it returns :macro:`SFPARSE_ERR_EOF`, all parameters
    have read, and caller can continue to read rest of the values.  If
    it returns :macro:`SFPARSE_ERR_PARSE`, it encountered fatal error
    while parsing field value.
