_MemFill( ) API Library Routine
Fills an area of memory starting at the location pointed to by ptr with length copies of the byte in character.
void _MemFill(void FAR *ptr, int character, unsigned int length)
void FAR *ptr; /* Starting point for fill. */
int character; /* Character for fill. */
unsigned int length; /* How many bytes to fill. */
Example
The following example uses _MemFill( ) to duplicate the functionality of the Visual FoxPro function REPLICATE( ).
Visual FoxPro Code
SET LIBRARY TO MEMFILL
x = xREPLICATE("x", 120)
? x
? LEN(x)
C Code
#include <pro_ext.h>
FAR Example(ParamBlk FAR *parm)
{
char FAR *rep;
char c = *(char *) _HandToPtr(parm->p[0].val.ev_handle);
rep = _Alloca((int) parm->p[1].val.ev_long + 1);
_MemFill(rep, c, (int) parm->p[1].val.ev_long);
rep[parm->p[1].val.ev_long] = '\0';
_RetChar(rep);
}
FoxInfo myFoxInfo[] = {
{"XREPLICATE", (FPFI) Example, 2, "C,I"},
};
FoxTable _FoxTable = {
(FoxTable FAR *) 0, sizeof(myFoxInfo)/sizeof(FoxInfo), myFoxInfo
};
