| The function <STRONG>new_field</STRONG> allocates a new field and initializes it from |
| the parameters given: height, width, row of upper-left corner, column |
| of upper-left corner, number off-screen rows, and number of additional |
| working buffers. |
| |
| The function <STRONG>dup_field</STRONG> duplicates a field at a new location. Most |
| attributes (including current contents, size, validation type, buffer |
| count, growth threshold, justification, foreground, background, pad |
| character, options, and user pointer) are copied. Field status and the |
| field page bit are not copied. |
| |
| The function <STRONG>link_field</STRONG> acts like <STRONG>dup_field</STRONG>, but the new field shares |
| buffers with its parent. Attribute data is separate. |
| |
| The function <STRONG>free_field</STRONG> de-allocates storage associated with a field. |
| |
| |
| </PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE> |
| The functions <STRONG>new_field</STRONG>, <STRONG>dup_field</STRONG>, <STRONG>link_field</STRONG> return <STRONG>NULL</STRONG> on error. |
| They set <STRONG>errno</STRONG> according to their success: |
| |
| <STRONG>E_OK</STRONG> The routine succeeded. |
| |
| <STRONG>E_BAD_ARGUMENT</STRONG> |
| Routine detected an incorrect or out-of-range argument. |
| |
| <STRONG>E_SYSTEM_ERROR</STRONG> |
| System error occurred, e.g., malloc failure. |
| |
| The function <STRONG>free_field</STRONG> returns one of the following: |
| |
| <STRONG>E_OK</STRONG> The routine succeeded. |
| |
| <STRONG>E_BAD_ARGUMENT</STRONG> |
| Routine detected an incorrect or out-of-range argument. |
| |
| <STRONG>E_CONNECTED</STRONG> |
| field is connected. |

| These routines emulate the System V forms library. They were not |
| supported on Version 7 or BSD versions. |
| |
| It may be unwise to count on the set of attributes copied by <STRONG>dup_field</STRONG> |
| being portable; the System V forms library documents are not very |
| explicit about what gets copied and what does not. |
