PA_GetTextVariable

version 2003

PA_GetTextVariable (aVariable; theText) → long

The routine PA_GetTextVariable puts the content of the variable aVariable in the data pointed to by theText and returns its length (max 32000).

If aVariable has not the kind eVK_Text , the routine returns 0 and theText is returned unchanged.

If text size is unknown, call the function a first time with theText equal to zero. The returned value will be the size of the needed buffer. Allocate the buffer and call the function again with the correct buffer.

Depending of default settings or of previous calls to PA_UseMacCharacters or PA_UseANSICharacters , theText will contain Macintosh or ANSI characters.

Get a text variable.

   char   *theText;
   long   textSize;
 
   // First call the routine with a nil pointer to get the text size
      textSize = PA_GetTextVariable(aVariable, 0L);
   // Then allocate the buffer
      theText = malloc(textSize);
   // If it is ok, get the text value
      textSize = PA_GetTextVariable(aVariable, theText);
   // Work with the text
      /* . . . */
   // Cleanup
      free(theText);
