/** Simple command line parser.
10 years ago
Supports flags that can be specified as -foo, --foo, --no-foo, -no-foo, etc
And integers, strings that can be specified as -foo=4, -foo blah, etc
No support for short command line options (but we may get that in the
future.)
Usage (for a program with a single flag argument 'foo'):
int main(int argc, char **argv) {
gpr_cmdline *cl;
int verbose = 0;
cl = gpr_cmdline_create("My cool tool");
gpr_cmdline_add_int(cl, "verbose", "Produce verbose output?", &verbose);
gpr_cmdline_parse(cl, argc, argv);
gpr_cmdline_destroy(cl);
if (verbose) {
gpr_log(GPR_INFO, "Goodbye cruel world!");
}
return 0;
} */
