_StrCpy( ) API Library Routine
Copies a null-terminated string from src to dest.
void _StrCpy(char FAR *dest, char FAR *src)
char FAR *dest; /* Destination location. */
char FAR *src; /* Source location. */
Remarks
_StrCpy( ) doesn't support overlapping moves. Overlapping moves are required when src and dest have some bytes in common. If overlapping moves are required, use _MemMove( ).
For more information on how to create an API library and integrate it with Visual FoxPro, see Accessing the Visual FoxPro API.
Example
The following example is passed a Visual FoxPro array of type Character. It then replaces the second element using _Store( ).
Before calling MYFUNC( ), the Visual FoxPro example code creates an array and initializes it to type Character. MYFUNC( ) passes this array by reference.
Visual FoxPro Code
SET LIBRARY TO STRCPY
? STRCPY("Hello", " world") && returns "Hello world"
C Code
#include <pro_ext.h>
FAR Example(ParamBlk FAR *parm)
{
#define p0 (parm->p[0].val)
#define p1 (parm->p[1].val)
if (!_SetHandSize(p0.ev_handle, p0.ev_length + p1.ev_length))
_Error(182); // "Insufficient memory"
_HLock(p0.ev_handle);
_HLock(p1.ev_handle);
((char FAR *) _HandToPtr(p1.ev_handle))[p1.ev_length] = '\0';
_StrCpy((char FAR *) _HandToPtr(p0.ev_handle) + p0.ev_length,
_HandToPtr(p1.ev_handle));
_RetChar(_HandToPtr(p0.ev_handle));
_HUnLock(p0.ev_handle);
_HUnLock(p1.ev_handle);
}
FoxInfo myFoxInfo[] = {
{"STRCPY", (FPFI) Example, 2, "C,C"},
};
FoxTable _FoxTable = {
(FoxTable FAR *) 0, sizeof(myFoxInfo)/sizeof(FoxInfo), myFoxInfo
};
