const is useful when you need to import a constant value from some library where it was compiled in. Or if it is used with pointers. Or if it is an array of constant values accessed through a variable index value. Otherwise, const has no advantages over #define. 它们不一样。 const只是...

Currently adding to pointers doesn't work: stdin:1:37-38: ERROR: The + operator can not be used on expressions of types cast, integer BEGIN { $a = (uint16*) 123; $b = $a + 5; } In C adding to a pointer uses the pointee size to increment, so: ...
You can direct MATLAB to autodefine the type and shape of specific argument types by using clibgen.generateLibraryDefinition and clibgen.buildInterface name-value arguments. The options are: To treat all const character pointers in the library as null-terminated C strings, set the TreatConstChar...
