_EdInsert( ) API Library Routine


void _EdInsert(WHANDLE wh, TEXT theStr, unsigned long Bytes) WHANDLE wh; / Handle of editing window. / TEXT theStr; /* Address of beginning of insertion text. / unsigned long Bytes; / Number of bytes to insert. */

void _EdInsert(WHANDLE wh, TEXT *theStr, unsigned long Bytes)
WHANDLE wh;            /* Handle of editing window. */
TEXT *theStr;               /* Address of beginning of insertion
 text. */
unsigned long Bytes;         /* Number of bytes to insert. */

The following example opens an editing session for a file specified by a parameter and inserts the line of text "Hello, world" as the new fourteenth line in the file.
