WSGetData (C 函数)
int WSGetData(WSLINK link,char *b,int len,int *count)
从由 link 指定的 WSTP 连接中获取文本数据,把结果存在最大长度为 len 的缓冲区 b 中,并把实际读取的字节数存在 count 中.
范例
基本范例 (1)
#include "wstp.h"
/* read data from a link in textual form */
void f(WSLINK lp)
{
int size, count;
char *buff;
switch(WSGetType(lp))
{
case WSTKSTR:
if(! WSBytesToGet(lp, &size))
{
/* unable to read the number of bytes from lp */
return;
}
buff = (char *)malloc(size * sizeof(char));
if(buff == (char *)0)
{
/* unable to allocate mmemory */
return;
}
if(! WSGetData(lp, buff, size &count))
{
/* unable to read the string data from lp */
free(buff);
return;
}
/* ... */
free(buff);
break;
}
/* ... */
}
