Arduino没有匹配功能来调用

Question

I have created program for my arduino uno, but I cannot compile it. Program based on IRemote IRecord example, and SD example.

CODE:

void sendCode(int repeat) {
   strcodeValue = String(codeValue);
   char filename[strcodeValue.length()+1];
   strcodeValue.toCharArray(filename, sizeof(filename));

   if (SD.exists(filename)) {   
   File myFile = SD.open(filename);
   if (myFile) {
    while (myFile.available(filename)) {
      codeValue = myFile.read();
    }
    myFile.close();
  }
   }
...
}

ERRORS:

IRrecord.ino: In function 'void sendCode(int)':
IRrecord.ino:130:37: error: no matching function for call to 'File::available(char [(((sizetype)<anonymous>) + 1)])'
IRrecord.ino:130:37: note: candidate is:
In file included from IRrecord.ino:18:0:
C:\Program Files (x86)\Arduino\libraries\SD\src/SD.h:38:15: note: virtual int File::available()
   virtual int available();
               ^
C:\Program Files (x86)\Arduino\libraries\SD\src/SD.h:38:15: note:   candidate expects 0 arguments, 1 provided
Error compiling.

File name will be read from IR Sensor.

Can anyone help me?

Answer 1

It surely looks like

while (myFile.available(filename)) {

should read

while (myFile.available()) {
