Dear sir i have tried copying binary file of my firmware in to buffer but its not copying completely please help me in this

copying part of my code

Code:

              if ((fp = fopen("/home/usb/FPR/firmware/fw.bix", "rb"))==NULL){
                printf("Cannot open file \n");
                }

                int fileLen;

                //Get file length
                fseek(fp, 0, SEEK_END);
                fileLen=ftell(fp);
                fseek(fp, 0, SEEK_SET);


                printf("\nfileLen = %d\n", fileLen);

                fread(buf, fileLen, 1 ,fp);

                cBuf = (const char*) buf;

                int len = strlen(cBuf);

                printf("\nBuf_len_aftr_Write = %d\n",len);


                while(len!=0)
                {
                printf("%c", *cBuf);
                len--;
                }

                int orglen = size;

                printf("\n\n");

                while(orglen!=0)
                {
                printf("%c", *buf);
                orglen--;
                }


                fclose(fp);

thanks

Don't use strlen, use the return value of fread... also check for EOF/errors. Manual is your friend, enter this command: man 3 fread

Also add a part like this:

Code:

void *buf= malloc (fileLen);
if (!buf) {
    fprintf (stderr, "Error in malloc(%d)\n", (int)fileLen);
    exit (99);
}
