mallocsizet
Mallocsizet is a typedef or alias used in some C and C++ codebases to denote the size of a memory block allocated by malloc and related functions. It is not part of the C or C++ standards and is not universally adopted, but it appears in projects that want to distinguish allocator-reported sizes from other size concepts.
Typically, mallocsizet is defined as an unsigned integer type chosen to be compatible with size_t. In practice,
Mallocsizet is often used in APIs that wrap or interact with malloc-like functions, where functions return
Portability considerations arise because mallocsizet is not standardized. For portable code, size_t is generally preferred for
- size_t
- allocator-specific size queries
