WebThe function aligned_alloc () is the same as memalign (), except for the added restriction that size should be a multiple of alignment . The obsolete function valloc () allocates size bytes and returns a pointer to the allocated memory. The memory address will be a multiple of the page size. Webchange ALLOC_* opcodes to expressions; drop code alignment requirement (no reason for function text to be aligned) drop length field from function descriptor (just assume it runs until the next function) look for common bytecode sequences; look for often-used strings (eg in allcompile.ts) and add them to bytecode.md WebIt can be used if the memory to be allocated is needed to be aligned at certain boundaries which can't be satisfied by malloc () or calloc (). malloc () and calloc () functions allocate memory that's suitably aligned for any object type (i.e. the alignment is alignof (max_align_t) ). But with aligned_alloc () greater alignments can be requested. colton underwood charity
