pyd.ftype

This module contains template for inferring the number of arguments, the return type, and argument types of an arbitrary function pointer.

This module was automatically generated by ftype.py

template NumberOfArgs(Tf)
This template will attempt to determine the number of arguments the supplied function pointer or delegate type takes. It supports a maximum of 10 arguments.

Example:
 void fnWithThreeArgs(byte a, short b, int c) {}
 const uint numArgs = NumberOfArgs!(typeof(&fnWithThreeArgs));


template ReturnType(Tf)
This template will attempt to discern the return type of the supplied function pointer or delegate type. It supports callables with a maximum of 10 arguments.

Example:
 uint returnsANumber() { return 42; }
 alias ReturnType!(typeof(&returnsANumber)) RType; // RType == uint


template ArgType(Tf,uint n)
This template will attempt to extract the type of the nth argument of the given function pointer or delegate type. It supports callables with up to 10 arguments.

Example:
 void intShortBool(int a, short b, bool c) {}
 alias ArgType!(typeof(&intShortBool), 2) TArg2; // TArg2 == short


template MIN_ARGS(alias fn)
This template will attempt to determine the minimum number of arguments a function can accept. Note that this accepts an alias parameter rather than a function pointer type, as the function and delegate types contain no information about default arguments.
