uintptrt

uintptrt is not a widely recognized standard type name in mainstream programming languages. It is likely a misspelling or shorthand for either uintptr_t, the C standard type, or Go’s uintptr. As such, articles about uintptrt typically refer to one of these established concepts rather than a distinct, universally defined type.

In C, uintptr_t is defined in the header stdint.h as an unsigned integer type guaranteed to be wide enough to hold a pointer. Its primary purpose is to enable safe and portable conversions between pointers and integers in low-level code, such as address manipulation, hashing, serialization, or interfacing with hardware. The exact width of uintptr_t is implementation-dependent, and while you can convert a pointer to uintptr_t and back, you should be mindful that arithmetic on the resulting integer is implementation-defined and may not be portable across platforms.

In Go, uintptr is an unsigned integer type capable of holding a pointer’s value. It is intended for low-level operations that require pointer representations, such as certain unsafe or performance-oriented tasks. It is not a real pointer and should not be used to perform generic pointer arithmetic or to extend the lifetime of objects with the garbage collector. Converting a pointer to a uintptr and holding onto that value can disconnect the pointer from GC tracking, so care is needed to recover the original pointer before dereferencing.

If you encountered the term uintptrt in documentation, it is advisable to verify whether the reference actually means uintptr (Go) or uintptr_t (C) and to consult the language’s standard library or compiler documentation for precise semantics. See also uintptr_t, uintptr.
