Function svn_opt_parse_revprop 

pub unsafe extern "C" fn svn_opt_parse_revprop(
    revprops: *mut *mut apr_hash_t,
    revprop_spec: *const c_char,
    pool: *mut apr_pool_t,
) -> *mut svn_error_t

Parse revprop key/value pair from @a revprop_spec (name[=value]) into @a revprops, making copies of both with @a pool. If @a revprops is @c NULL, allocate a new apr_hash_t in it. @a revprops maps const char * revprop names to svn_string_t * revprop values for use with svn_repos_get_commit_editor5 and other get_commit_editor APIs.
