Hello, I’m trying to write program with C
library, which uses ioctl
to manage SPI interface on the board. So after getting some error via std.c._errno()
, I don’t know what represents this number after compilation. How can I transform it to []u8
? In C I might use strerror(errno: c_int)
. Is in Zig any alternatives?
std.posix.errno returns an enum value from the errno. Using @tagName
we can get the enum value name.
const errno = ...;
const name: []const u8 = @tagName(std.posix.errno(errno));

Works well
std.debug.print("Error: {s}\n", .{@tagName(std.posix.errno(std.c._errno().*))});
