From 39f9121339559738cba5130c818e8920e1a2fa16 Mon Sep 17 00:00:00 2001 From: Andrew Clayton Date: Wed, 21 May 2025 04:13:11 +0100 Subject: Use NULL instead of 0 as null pointer constant MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit GCC 15 enabled "-Wzero-as-null-pointer-constant" for C, which checks for places where '0' has been used as a null pointer constant. This showed a few places in Unit where we were using '0' instead of the more correct NULL macro. E.g. $ make -j4 EXTRA_CFLAGS=-Wzero-as-null-pointer-constant ... src/nxt_buf.c: In function ‘nxt_buf_mmap_alloc’: src/nxt_buf.h:192:21: error: zero as null pointer constant [-Werror=zero-as-null-pointer-constant] 192 | (bm)->start = 0; \ | ^ src/nxt_buf.c:135:9: note: in expansion of macro ‘nxt_buf_mem_set_size’ 135 | nxt_buf_mem_set_size(&b->mem, size); | ^~~~~~~~~~~~~~~~~~~~ Signed-off-by: Andrew Clayton --- src/nxt_unit.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'src/nxt_unit.c') diff --git a/src/nxt_unit.c b/src/nxt_unit.c index 2f399678..7d523beb 100644 --- a/src/nxt_unit.c +++ b/src/nxt_unit.c @@ -716,7 +716,7 @@ nxt_unit_ctx_init(nxt_unit_impl_t *lib, nxt_unit_ctx_impl_t *ctx_impl, ctx_impl->req.req.unit = &lib->unit; ctx_impl->read_port = NULL; - ctx_impl->requests.slot = 0; + ctx_impl->requests.slot = NULL; return NXT_UNIT_OK; } -- cgit
