本文介绍了一个用于检查指定进程（如MobileEngine.exe）是否正在运行的脚本实现。该脚本通过调用系统的tasklist命令并将结果保存到文件中，然后读取此文件来判断进程是否处于运行状态。如果进程未运行，则输出错误信息并终止脚本。

 
 
 
 
checkprocess() 
 { 
 char command[1024]; 
 int i, total = 0; 
 char buffer[12], ch; 
 char *filename = lr_eval_string("C:\\tasklist_{pTime}.txt"); 
 long file_stream; 
  
//Run a system command to open up a DOS prompt and tasklist 
//Save it to a file 
  
sprintf(command, "tasklist /FI \"IMAGENAME eq MobileEngine.exe\" 
       /FI \"STATUS eq running\" /FO TABLE /NH > %s", filename); 
system(command); 
  
// open file and check for errors opening it. 
  
if ((file_stream = fopen(filename, "r")) == NULL ) { 
lr_error_message("Cannot open %s", filename); 
 return -1; 
 } 
  
//read the file stream information - place in loop. 
  
for(i=0; (i<NUM_CHARS) && (feof(file_stream) == 0); i++) { 
     ch = fgetc(file_stream); /* Read in the next character */
     buffer[i] = ch; /* Place the new char at the end of the buffer */
 }  
  
/* Add null to end the buffer converting it to a string */
  
buffer[i] = NULL; 
lr_output_message("First %d characters of file %s are \"%s\"", 
     NUM_CHARS, filename, buffer); 
  
if (fclose(file_stream)){ 
 lr_error_message("Error closing file %s", filename); 
 }; 
  
// Now we either have something in the buffer or not. 
// We are looking for the string "MobileEngine" in this case 
// Either way, delete the temp file when done. 
  
if (strcmp(buffer, "\nMobileEngine") != 0) { 
 lr_error_message("The process is not running. Aborting Script..."); 
 sprintf(command, "DEL %s", filename ); 
 // lr_error_message("%s", command); 
 system(command); 
 return -1; 
 } 
 else{ 
 lr_output_message("The process is running. Continue..."); 
 sprintf(command, "DEL %s", filename ); 
 // lr_error_message("%s", command); 
 system(command); 
 }; 
  
return 0; 
  
}
