From 361fbcc14acc4a3bed9161934f2524db8ac2069e Mon Sep 17 00:00:00 2001 From: Christopher Faulet Date: Tue, 21 Sep 2021 15:45:05 +0200 Subject: [PATCH] MINOR: htx: Add a function to know if the free space wraps the htx_space_wraps() function may now be used to know if the free space of an HTX message wraps. It does the same as b_space_wraps(). --- include/haproxy/htx.h | 11 +++++++++++ 1 file changed, 11 insertions(+) diff --git a/include/haproxy/htx.h b/include/haproxy/htx.h index 0faf29646..c7ae30891 100644 --- a/include/haproxy/htx.h +++ b/include/haproxy/htx.h @@ -606,6 +606,17 @@ static inline uint32_t htx_free_data_space(const struct htx *htx) return (free - sizeof(struct htx_blk)); } +/* Returns non-zero only if the HTX message free space wraps */ +static inline int htx_space_wraps(const struct htx *htx) +{ + uint32_t headroom, tailroom; + + headroom = (htx->end_addr - htx->head_addr); + tailroom = (htx_pos_to_addr(htx, htx->tail) - htx->tail_addr); + + return (headroom && tailroom); +} + /* Returns the maximum size for a block, not exceeding bytes. may be * set to -1 to have no limit. */
