CAPLを使用してテキストファイルから文字列を読み取る方法は？

Question

CAPLを使用して特定のテキストファイルから文字列を読み取る必要があります。テキストファイルから読み込んでバッファに格納するCANoe/CAPL関数はありますか？そうでない場合、これを達成するための一般的な関数を作成する方法は？

Answer 1

fileGetStringをご覧ください。以下は、CAPLヘルプメニューのサンプルコードです。

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); 
}
