syntax: functions require return type. remove `->` The purpose of this is: * Only one way to do things * Changing a function with void return type to return a possible error becomes a 1 character change, subtly encouraging people to use errors. See #632 Here are some imperfect sed commands for performing this update: remove arrow: ``` sed -i 's/\(\bfn\b.\)-> /\1/g' $(find . -name ".zig") ``` add void: ``` sed -i 's/\(\bfn\b.\))\s{/\1) void {/g' $(find ../ -name "*.zig") ``` Some cleanup may be necessary, but this should do the bulk of the work. 2018-01-25 09:10:11 +00:00			`pub extern "c" fn getrandom(buf_ptr: &u8, buf_len: usize, flags: c_uint) c_int;`

improvements for windows and libc integration * standard library knows if it is linking against libc and will sometimes call libc functions in that case instead of providing redundant definitions * fix infinite loop bug when resolving use declarations * allow calling the same C function from different C imports. closes #277 * push more logic from compiler to std/bootstrap.zig * standard library provides way to access errno closes #274 * fix compile error in standard library for windows * add implementation of getRandomBytes for windows 2017-03-23 06:59:58 +00:00			`pub const _errno = __errno_location;`
