== `error.hpp`
[#error]
The error header provides two error categories:
[source,cpp]
----
// Errors used for utf8 <-> UCS-2 conversions.
enum utf8_conv_error
{
insufficient_buffer = 1,
invalid_character,
};
extern const error_category& get_utf8_category();
static const error_category& utf8_category = get_utf8_category();
extern const error_category& get_exit_code_category();
/// An error category that can be used to interpret exit codes of subprocesses.
static const error_category& exit_code_category = get_exit_code_category();
}
----
The `get_exit_code_category` can be used as follows:
[source,cpp]
----
void run_my_process(filesystem::path pt, error_code & ec)
{
process proc(pt, {});
proc.wait();
ec.assign(proc.native_exit_code(), error::get_exit_code_category());
}
----
