_EdOpenFile( ) API Library Routine

Opens the specified file in a window, in order to begin an editing session.


WHANDLE _EdOpenFile(TEXT *filename, int mode)
TEXT *filename;            /* File to open. */
int mode;                     /* Mode option. */

The following mode options are available: FO_READONLY, FO_WRITEONLY, and FO_READWRITE.

For more information on how to create an API library and integrate it with Visual FoxPro, see Accessing the Visual FoxPro API.

The following example opens an editor session for a file specified by a parameter.

Visual FoxPro Code

SET LIBRARY TO EDOPEN  
= EDOPEN("x")  && opens editor session for file "x"

C Code

#include <pro_ext.h>

FAR Example(ParamBlk FAR *parm)
{
#define pFILENAME ((char FAR *) _HandToPtr(parm->p[0].val.ev_handle))

   WHANDLE wh;

   if (!_SetHandSize(parm->p[0].val.ev_handle,
      parm->p[0].val.ev_length+1))
   {
      _Error(182); // "Insufficient memory"
   }
   pFILENAME[parm->p[0].val.ev_length] = '\0';

   _HLock(parm->p[0].val.ev_handle);
   wh = _EdOpenFile(pFILENAME, FO_READWRITE);
   _HUnLock(parm->p[0].val.ev_handle);
}

FoxInfo myFoxInfo[] = {
   {"EDOPEN", (FPFI) Example, 1, "C"},
};
FoxTable _FoxTable = {
   (FoxTable FAR *) 0, sizeof(myFoxInfo)/sizeof(FoxInfo), myFoxInfo
};
