Miscellaneous Library Functions                form_field_new(3X)



NAME
     form_field_new - create and destroy form fields

SYNOPSIS
     #include 
     FIELD *new_field(int height, int width,
                      int toprow, int leftcol,
                      int offscreen, int nbuffers);
     FIELD *dup_field(FIELD *field, int toprow, int leftcol);
     FIELD *link_field(FIELD *field, int toprow, int leftcol);
     int free_field(FIELD *field);

DESCRIPTION
     The function new_field 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 dup_field duplicates a field at a new location.
     Most  attributes  (including current contents, size, valida-
     tion 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 link_field acts like  dup_field,  but  the  new
     field  shares  buffers  with  its parent.  Attribute data is
     separate.

     The function free_field de-allocates storage associated with
     a field.

RETURN VALUE
     The function, new_field, dup_field, link_field  return  NULL
     on error.  They set errno according to their success:

     E_OK The routine succeeded.

     E_BAD_ARGUMENT
          Routine detected an incorrect or out-of-range argument.

     E_SYSTEM_ERROR
          System error occurred, e.g., malloc failure.

     The function free_field returns one of the following:

     E_OK The routine succeeded.

     E_BAD_ARGUMENT
          Routine detected an incorrect or out-of-range argument.

     E_CONNECTED

          field is connected.

NOTES
     The header file  automatically includes  the  header
     file .

PORTABILITY
     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
     dup_field  being  portable; the System V forms library docu-
     ments are not very explicit about what gets copied and  what
     does not.
