Following are the measures that can be adopted to avoid errors in file processing-

ferror() function can be used to detect any error during file accessing.This function will return a zero when there is no error or vice-versa.

FILE *fptr

if(ferror(fptr)==0)

printf(“n The file is available for processing”);

else

printf(“n Error in accessing file”);

To verify whether a file exists in the disks,the following definitions will help.

if(fptr==NULL)

printf(“n No content or file does not exist”);
