"CSizeT" (Compiled Type)

"CSizeT"

represents the C size_t type.

Details

  • "CSizeT" is a macro that is replaced with a platform-specific concrete type. On most platforms, "CSizeT" is a macro for "UnsignedInteger64".

Examples

Basic Examples  (3)

Compile a function that takes a "CSizeT" as input:

Wolfram Language code: cf = FunctionCompile[Function[Typed[arg, "CSizeT"], arg]]
Wolfram Language code: cf[100]

Compile a program that calls the C standard library function malloc on a size_t:

Wolfram Language code: cf = FunctionCompile[Function[Typed[arg, "CSizeT"], Cast[LibraryFunction["malloc"][arg], "UnsignedInteger64", "BitCast"]]]
Wolfram Language code: cf[10]

Create a constant with type "CSizeT":

Wolfram Language code: cf = FunctionCompile[Function[{}, Typed[12, "CSizeT"]]]
Wolfram Language code: cf[]
