WSPutRealNumberAsUCS2String (C 函数)

int WSPutRealNumberAsUCS2String(WSLINK l, const unsigned short *s)

将一个编码为 UCS2 字符串 s 的浮点数发送到由 l 指定的 WSTP 连接.

更多信息

  • 将数字 s"3.14159" 的形式发送.
  • 若发生错误,则 WSPutRealNumberAsUCS2String() 返回0;若函数成功,则返回非零值.
  • WSTP 的标头文件 wstp.h 已对 WSPutRealNumberAsUCS2String() 作出声明.

范例

基本范例  (1)

#include "wstp.h"

/* A function to put the expression Sqrt[2.75] to a link */

void f(WSLINK l)
{
    unsigned short theNumber[5];

    theNumber[0] = '2';
    theNumber[1] = '.';
    theNumber[2] = '7';
    theNumber[3] = '5';
    theNumber[4] = 0;

    if(! WSPutFunction(l, "Sqrt", 1))
    { /* Unable to put Sqrt[] to the link */ }

    if(! WSPutRealNumberAsUCS2String(l, theNumber))
    { /* Unable to put the number to the link */}

    if(! WSEndPacket(l))
    { /* Unable to put the end-of-packet sequence to l */ }

    if(! WSFlush(l))
    { /* Unable to flush any output buffered in l */ }
