Function Documentation

int G_yes ( const char *  question,
int  dflt 

Ask a yes/no question.

This routine prints a question to the user, and expects the user to respond either yes or no. (Invalid responses are rejected and the process is repeated until the user answers yes or no.)
The default indicates what the RETURN key alone should mean. A default of 1 indicates that RETURN means yes, 0 indicates that RETURN means no. The question will be appended with ''(y/n) '', and, if default is not -1, with ''[y] '' or ''[n] '', depending on the default.

0 for No
1 for Yes
