76 | * gcc see's this problem and issues a warning for the line. | |
77 | * | |
78 | * Why is this a big deal you say? Because both of them are right | |
79 | * and if you have -Werror enabled then all calls to write | |
80 | * generate a build error and the build stops. | |
81 | * | |
82 | * clang has helpfully allowed this construct: | |
83 | * (void)write(...) | |
84 | * to tell the compiler yeah I know it has a return value | |
85 | * I don't care about it at this time. | |
86 | * gcc doesn't have this ability. | |
87 | * | |
88 | * This code was written such that it didn't care about the | |
89 | * return value from write. At this time do I want | |
90 | * to go through and fix and test this code for correctness. | |
91 | * So just wrapper the bad behavior and move on. | |
