Too few arguments to function 'int fclose(FILE*)' - c++

Question

Hello I am a beginner of C language for microprocessors. I want to read a ''.bmp'' file in order to apply line detection on it. I have declared a function to read the image. This error occurs when compile button is pushed:
#include "esp_camera.h"
#include "Arduino.h"
#include "FS.h" // SD Card ESP32
#include "SD_MMC.h" // SD Card ESP32
#include "soc/soc.h" // Disable brownour problems
#include "soc/rtc_cntl_reg.h" // Disable brownour problems
#include "driver/rtc_io.h"
#include <EEPROM.h> // read and write from flash memory
#include <SPI.h>
void imageReader(const char *imgName,
int *height,
int *width,
int *bitdepth,
unsigned char *header,
unsigned char *_colortable,
unsigned char *buf
) // READ AN IMAGE
{
int i;
fs::FS &fs = SD_MMC; //
FILE *file;
file = fopen(imgName,"rb"); // read imgName file ( it is a picture in .bmp format )
if(!file){
Serial.printf("Unable to read image");
}
for(i=0 ; i<54 ; i++){
header[i]=getc(file);
}
*width = *(int * )& header[18]; // width information of the image
*height = *(int * )& header[22]; // height information of image
*bitdepth = *(int *)& header[28];
if(*bitdepth<=8){
fread(_colortable,sizeof(unsigned char),1024,file);
}
fread(buf,sizeof(unsigned char),( 1600 * 1200 ) ,file);
fclose();
}
It gives this error. too few arguments to function 'int fclose(FILE*)'

The fclose() function needs to know which file to close. You need to tell it that by supplying "file" as an argument. You want to use fclose(file).
