This is the type checked by validation - functions. The types are as follows: - - TYPE_ALNUM - Alphanumeric data. Requires a third <B>int</B> argument, a - minimum field width. - - TYPE_ALPHA - Character data. Requires a third <B>int</B> argument, a - minimum field width. - - TYPE_ENUM - Accept one of a specified set of strings. Requires a - third <B>(char</B> <B>**)</B> argument pointing to a string list; a - fourth <B>int</B> flag argument to enable case-sensitivity; - and a fifth <B>int</B> flag argument specifying whether a - partial match must be a unique one (if this flag is - off, a prefix matches the first of any set of more - than one list elements with that prefix). Please - notice that the string list is not copied, only a - reference to it is stored in the field. So you should - avoid to use a list that lives in automatic variables - on the stack. - - TYPE_INTEGER - Integer data, parsable to an integer by <B>atoi(3)</B>. - Requires a third <B>int</B> argument controlling the preci- - sion, a fourth <B>long</B> argument constraining minimum - value, and a fifth <B>long</B> constraining maximum value. - If the maximum value is less or equal the minimum - value, the range is simply ignored. On return the - field buffer is formatted according to the <B>printf</B> - format specification ".*ld", where the '*' is - replaced by the precision argument. For details of - the precision handling see <B>printf's</B> man-page. - - TYPE_NUMERIC - Numeric data (may have a decimal-point part). - Requires a third <B>int</B> argument controlling the preci- - sion, a fourth <B>double</B> argument constraining minimum - value, and a fifth <B>double</B> constraining maximum value. - If your system supports locale's, the decimal point - character to be used must be the one specified by - your locale. If the maximum value is less or equal - the minimum value, the range is simply ignored. On - return the field buffer is formatted according to the - <B>printf</B> format specification ".*f", where the '*' is - replaced by the precision argument. For details of - the precision handling see <B>printf's</B> man-page. - - TYPE_REGEXP - Regular expression data. Requires a regular expres- - sion <B>(char</B> <B>*)</B> third argument; the data is valid if - the regular expression matches it. Regular expres- - sions are in the format of <B><A HREF="regcomp.3x.html">regcomp(3x)</A></B> and - <B><A HREF="regexec.3x.html">regexec(3x)</A></B>. Please notice that the regular expres- - sion must match the whole field. If you have for - example an eight character wide field, a regular - expression "^[0-9]*$" always means that you have to - fill all eight positions with digits. If you want to - allow fewer digits, you may use for example "^[0-9]* - *$" which is good for trailing spaces (up to an empty - field), or "^ *[0-9]* *$" which is good for leading - and trailing spaces around the digits. - - TYPE_IPV4 - An Internet Protocol Version 4 address. This requires - no additional argument. It is checked whether or not - the buffer has the form a.b.c.d, where a,b,c and d - are numbers between 0 and 255. Trailing blanks in the - buffer are ignored. The address itself is not vali- - dated. Please note that this is an ncurses extension. - This field type may not be available in other curses - implementations. - - It is possible to set up new programmer-defined field - types. See the <B><A HREF="form_fieldtype.3x.html">form_fieldtype(3x)</A></B> manual page. - - -</PRE> -<H2>RETURN VALUE</H2><PRE> - The functions <B>field_type</B> and <B>field_arg</B> return <B>NULL</B> on - error.
