The explain_buffer_errno_setgroups function is used to obtain an explanation of an error returned by the setgroups(2) system call. The least the message will contain is the value of strerror(errnum)
, but usually it will do much better, and indicate the underlying cause in more detail.
sb | The string buffer to print the message into. If a suitable buffer is specified, this function is thread safe. |
errnum | The error value to be decoded, usually obtained from the errno global variable just before this function is called. This is necessary if you need to call any code between the system call to be explained and this function, because many libc functions will alter the value of errno. |
data_size | The original data_size, exactly as passed to the setgroups(2) system call. |
data | The original data, exactly as passed to the setgroups(2) system call. |
