Function cCharSignedness [src]

Default signedness of char for the native C compiler for this target Note that char signedness is implementation-defined and many compilers provide an option to override the default signedness e.g. GCC's -funsigned-char / -fsigned-char

Prototype

pub fn cCharSignedness(target: *const Target) std.builtin.Signedness

Parameters

target: *const Target
