From 72381db942dd00f4d69b2d9a50156a62f2c350da Mon Sep 17 00:00:00 2001 From: Lennart Poettering Date: Tue, 14 Feb 2023 13:40:40 +0100 Subject: [PATCH] mempool: introduce new helper pool_ptr() This new helper returns the beginning of the usable area of the pool object. For now this is only used once, a later commit will use it more. --- src/basic/mempool.c | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) diff --git a/src/basic/mempool.c b/src/basic/mempool.c index 29f72a8171..d934aa9547 100644 --- a/src/basic/mempool.c +++ b/src/basic/mempool.c @@ -13,6 +13,10 @@ struct pool { size_t n_used; }; +static void* pool_ptr(struct pool *p) { + return ((uint8_t*) ASSERT_PTR(p)) + ALIGN(sizeof(struct pool)); +} + void* mempool_alloc_tile(struct mempool *mp) { size_t i; @@ -54,7 +58,7 @@ void* mempool_alloc_tile(struct mempool *mp) { i = mp->first_pool->n_used++; - return ((uint8_t*) mp->first_pool) + ALIGN(sizeof(struct pool)) + i*mp->tile_size; + return (uint8_t*) pool_ptr(mp->first_pool) + i*mp->tile_size; } void* mempool_alloc0_tile(struct mempool *mp) {
