On success, returns the written character.

[edit] Example
Run this code
#include <cstdio> int main() { for (char c = 'a'; c != 'z'; c++) std::putchar(c); std::putchar('\n'); // putchar return value is not equal to the argument int r = 0x1070; std::printf("\n0x%x\n", r); r = std::putchar(r); std::printf("\n0x%x\n", r); }
Output:
abcdefghijklmnopqrstuvwxy 0x1070 p 0x70
