Hi,
I have developed a sample program in which I have allocating a buffer of 10 MB and writing buffer into SD card. After writing code I am closing file and free allocated buffer of 10 MB. Surprisingly even after closing the application 10 MB memory free is not reflected in /pfoc/meminfo. For all subsequent execution of same application doesn't leak additional 10 MB memory but same time holding 10 MB memory of the first-time execution. No other application is running along with this application.
I am using DM36x IPCamera RDK v. 4.1 V based on Linux Kernel 2.6.37. Please let me know how to resolve it.
Following is the application code.
//======================================Code Start============================================
#include <stdio.h>
#include <stdlib.h>
#define BUF_SIZE 1024 * 1024 * 10
#define FILE_PATH "/mnt/mmc/file1.txt"
unsigned char *arr;
int main()
{
int write_bytes;
int i;
FILE *fp;
arr = (unsigned char *)malloc((BUF_SIZE * sizeof(unsigned char)) + 1);
for (i = 0; i < BUF_SIZE; i++)
arr[i] = (unsigned char)i;
fp = fopen(FILE_PATH, "wb");
if(!fp)
{
printf("Error in opening the location\n");
exit(EXIT_FAILURE);
}
write_bytes = fwrite(arr, 1, BUF_SIZE, fp);
fclose(fp);
printf("bytes = %d\n\n\n", write_bytes);
free(arr);
return 0;
}
//======================================Code End============================================
