GetMem4
Reads four bytes from a memory address into a Long variable.
Syntax: GetMem4 Address , retVal
- Address
- required LongPtr. The address to read from.
- retVal
- required Long. The variable to receive the value read from Address.
The bytes are interpreted in the host’s native byte order — little-endian on x86 and x64. The address is read directly with no bounds or alignment check.
Common Errors
| Error | When |
|---|---|
94 (&H5E), Invalid use of Null | Address is Null |
Example
This example writes a 32-bit value to a buffer and reads it back with GetMem4.
Dim buf As LongPtr = AllocMem(4)
PutMem4 buf, &H12345678
Dim v As Long
GetMem4 buf, v ' v = &H12345678
FreeMem buf
