Function ql_sys_log_print 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn ql_sys_log_print(
    _log_id: c_int,
    prio: c_int,
    tag: *const c_char,
    fmt: *const c_char,
    ...
) -> c_int

Available on crate feature logging only.

Sends a formatted string to the log.

Originally provided by ql_sys_log.

Safety

This function is safe to call if both tag and fmt point to a valid null-terminated C string. The variadic parameters must be valid for the printf format string in fmt.
