为 Capl 函数 sysExecCmd 设置相对路径

Question

我有以下代码行。我想设置相对路径而不是硬编码路径，因为目前在下面的第二个参数中设置了-

sysExecCmd("Unlock_Ecu.bat","","D:\Program Files\ToolPath");

应替换为：

sysExecCmd("Unlock_Ecu.bat","","...\ToolPath");

如何在 Capl 的 sysExecCmd 函数中实现？

Answer 1

来自 sysExecCmd 文档（强调我的）：

To avoid absolute paths in CAPL code and to be independent of the execution platform, proceed as follows:

Add the application to be started to the User Files in CANoe Options dialog. At application call the absolute path can be resolved with the CAPL function GetUserFilePath.

示例：

char absPath[256];
GetUserFilePath("Unlock_Ecu.bat", absPath, 256);
SysExecCmd(absPath, "");

Answer 2

我通常会按照下面的方式进行：

variables
{
  char absPath[256];   // Holds Abs Path for current CFG file
  // Relative Path for ToolPath folder
  char ToolPath[100]= "\ToolPath\";
}

on preStart
{
  /* Get Abs path of current config file */
  GetUserFilePath("", absPath, 256);
  Exec_Batch();
}

void Exec_Batch()
{
  /* Get Absolute Path for executing Bat file */
  char absToolPath[256];
  strncat(absToolPath, absPath, strlen(absPath));
  strncat(absToolPath, ToolPath, strlen(absToolPath) + strlen(ToolPath)); 

  write("Executing Batch File");

  sysExecCmd("Unlock_Ecu.bat","",absToolPath);

  write("Finished execution of Batch File");
}
