[Alex Tran]

socket.c: In function ‘run_tests’:
socket.c:59:25: warning: ignoring return value of ‘strerror_r’ declared with 
attribute ‘warn_unused_result’ [-Wunused-result]
59 | strerror_r(-s->expect, err_string1, ERR_STRING_SZ);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
socket.c:60:25: warning: ignoring return value of ‘strerror_r’ declared with 
attribute ‘warn_unused_result’ [-Wunused-result]
60 | strerror_r(errno, err_string2, ERR_STRING_SZ);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
socket.c:73:33: warning: ignoring return value of ‘strerror_r’ declared with 
attribute ‘warn_unused_result’ [-Wunused-result]
