WSPutSymbol （C 函数）

int WSPutSymbol(WSLINK link,const char *s)

把由字符字符串 s 给定名称的符号写入由 link 指定的 WSTP 连接.

更多信息

  • 字符字符串必须以零字节结束，对应于 C 中的 ∖0.
  • 若发生错误，则 WSPutSymbol() 返回0；若函数成功，则返回非零值.
  • 若 WSPutSymbol() 失败，则使用 WSError() 检索错误代码.
  • WSTP 的标头文件 wstp.h 已对 WSPutSymbol() 作出声明.

范例

基本范例  (1)

#include "wstp.h"

/* send the expression Integrate[Sin[x],x] to a link */

void f(WSLINK lp)
{
    if(! WSPutFunction(lp, "Integrate", 2))
        { /* unable to put the function to lp */ }

    if(! WSPutFunction(lp, "Sin", 1))
        { /* unable to put the function to lp */ }

    if(! WSPutSymbol(lp, "x"))
        { /* unable to put the symbol to lp */ }

    if(! WSPutSymbol(lp, "x"))
        { /* unable to put the symbol to lp */ }

    if(! WSEndPacket(lp))
        { /* unable to send the end-of-packet indicator to lp */ }

    if(! WSFlush(lp))
        { /* unable to flush any outgoing data buffered in lp */ }
