The following example uses memcmp to compare two strings and checks if they are equal.
char* s1 = "access to shared transmission";
char* s2 = "access to transmission";
rc = memcmp( s1, s2, strlen(s1));
if (rc > 0)
lr_output_message("`%s' is greater than '%s'", s1, s2);
else if (rc < 0)
lr_output_message("`%s' is less than '%s'", s1, s2);
lr_output_message("'%s' is the same as '%s'\n", s1, s2);
'access to shared transmission' is less than 'access to transmission'
