Header File

Category
Input/output Routines
Prototype
void clearerr(FILE *stream);
Description
Resets error indication.
clearerr resets the named stream's error and end-of-file indicators to 0. Once the error indicator is set, stream operations continue to return error status until a call is made to clearerr or rewind. The end-of-file indicator is reset with each input operation.
Return Value
None.
Example
#include <stdio.h>
int main(void)
{
FILE *fp;
char ch;
/* open a file for writing */
fp = fopen("DUMMY.FIL", "w");
/* force an error condition by attempting to read */
ch = fgetc(fp);
printf("%c\n",ch);
if (ferror(fp))
{
/* display an error message */
printf("Error reading from DUMMY.FIL\n");
/* reset the error and EOF indicators */
clearerr(fp);
}
fclose(fp);
return 0;
}
