NAME

boolarg - parse boolean argument or ask user

SYNOPSIS

int boolarg (ptr,brk,prompt,defalt);
char **ptr,*brk,*prompt;
int defalt;

DESCRIPTION

Boolarg attempts to parse an argument from a string, passing the string pointer ptr and the break character set brk to the nxtarg(3) routine. If there is an argument parsed, and it is a legal boolean, then its value is returned by boolarg. If there is no argument, or it is not valid, then an error message is printed to stderr and the routine getbool(3) is passed the remaining arguments. The value of getbool is then returned by boolarg.

Boolarg is especially useful for parsing boolean values from argument lists in programs using the command interpreter, ci(3).
