Detailed Description

template<typename T1 = void, typename T2 = void>
struct thrust::project1st< T1, T2 >

project1st is a function object that takes two arguments and returns its first argument; the second argument is unused. It is essentially a generalization of identity to the case of a Binary Function.

#include <assert.h>
int x = 137;
int y = -137;
assert(x == pj1(x,y));
