PA_GetTextInArray


version 2003


PA_GetTextInArray (array; index; text) → long

Parameter Type Description
array PA_Variable Array to access
index long Index of the element to access
text char * Pointer to the text
Function result long Size of text in bytes

Description

The routine PA_GetTextInArray fills the data pointed to by text with the text data of the index element of the text array array , and returns the size of the text.

First, pass zero in text to get the size of the text, then allocate a buffer with the correct size and again call the routine passing it this buffer. See the example below.

If the array is not a eVK_ArrayText or if index is out of range, the routine returns 0 and leaves text unchanged.

PA_GetTextInArray

fills the data with Macintosh characters on Macintosh and ANSI characters under Windows, unless you have previously called the PA_UseMacCharacters or PA_UseAnsiCharacters function.

Example

Get the value of the current element (no error check in this sample).

   char   *buffer;
   long   size;
 
   size = PA_GetTextInArray( arr, PA_GetArrayCurrent( arr ), 0L );
   buffer = malloc( size );
   size = PA_GetTextInArray( arr, PA_GetArrayCurrent( arr ), buffer );
   /* . . . work with text buffer . . . */
   free( buffer );
