我需要使用CAPL从特定文本文件中读取字符串。是否有任何CANoe/CAPL函数从文本文件读取并将其存储在缓冲区中?如果不是,如何创建一个通用函数来实现这一点?如何使用CAPL从文本文件中读取字符串?

检出fileGetString。以下是CAPL帮助菜单中的示例代码。
variables
{
msTimer writeTimer;
long glbPeriod = 250;
dword glbHandle = 0;
long glbValue;
}
on Start
{
char buffer[64];
long ret;
//
// Opens the file in ASCII mode for read access.
//
// To determine the absolute path, the search procedure will be used.
// The file must be located in the directory of the databases or the
// configuration directory.
//
glbHandle = OpenFileRead ("Data.Txt",0);
if (glbHandle!=0)
{
//
// got to end of file ...
//
while (fileGetString(buffer,elcount(buffer),glbHandle)!=0) {};
//
// Get the last parameters
// (saved on disk after the end the last measurement)
//
glbValue = atol (buffer);
write ("Last value %d.",glbValue);
fileClose (glbHandle);
}
else
{
write ("File 'Data.Txt' was not opened for read access.");
}
//
// Open the file in ASCII mode for write access.
//
// The write path was not set using the function setWritePath(), so
// the configuration directory will be used instead. This is the
// default behavior.
//
glbHandle = OpenFileWrite ("Data.Txt",2);
if (glbHandle!=0)
{
setTimer (writeTimer,glbPeriod);
}
else
{
write ("File 'Data.Txt' was not opened for write access.");
}
}
on timer writeTimer
{
long randomValue;
char buffer [64];
if (glbHandle!=0)
{
randomValue = random (32767);
snprintf (buffer,elcount(buffer)," %d \n",randomValue);
filePutString (buffer, elcount(buffer),glbHandle);
setTimer (writeTimer,glbPeriod);
}
else
{
write ("Error, invalid file handle.");
}
}
on StopMeasurement
{
fileClose (glbHandle);
}
