From ccc4a2a5d85252c40e3af23a00d30d3653c46f58 Mon Sep 17 00:00:00 2001 From: pfg Date: Fri, 12 Jan 2018 17:36:19 +0000 Subject: [PATCH] MFC r327697, r327699: Use the __result_use_check attribute for reallocf(9). MFC r327751: Use the __result_use_check attribute also for reallocf(3). The GCC attribute causes a warning to be emitted if a caller of the function with this attribute does not use its return value. Unlike the traditional realloc, with reallocf(3) we don't have to check for NULL values but we still have to make sure the result is used. --- include/stdlib.h | 2 +- sys/sys/malloc.h | 2 +- 2 files changed, 2 insertions(+), 2 deletions(-) diff --git a/include/stdlib.h b/include/stdlib.h index eb794049ee8..0928c330b20 100644 --- a/include/stdlib.h +++ b/include/stdlib.h @@ -309,7 +309,7 @@ int radixsort(const unsigned char **, int, const unsigned char *, unsigned); void *reallocarray(void *, size_t, size_t) __result_use_check __alloc_size(2) __alloc_size(3); -void *reallocf(void *, size_t) __alloc_size(2); +void *reallocf(void *, size_t) __result_use_check __alloc_size(2); int rpmatch(const char *); void setprogname(const char *); int sradixsort(const unsigned char **, int, const unsigned char *, diff --git a/sys/sys/malloc.h b/sys/sys/malloc.h index b53066399d3..f94dd3b9547 100644 --- a/sys/sys/malloc.h +++ b/sys/sys/malloc.h @@ -184,7 +184,7 @@ void malloc_uninit(void *); void *realloc(void *addr, unsigned long size, struct malloc_type *type, int flags) __result_use_check __alloc_size(2); void *reallocf(void *addr, unsigned long size, struct malloc_type *type, - int flags) __alloc_size(2); + int flags) __result_use_check __alloc_size(2); struct malloc_type *malloc_desc2type(const char *desc); #endif /* _KERNEL */ -- 2.45.0
