Usage Guidelines
•
The clearerr function might be implemented as a macro in a future release.
•
The end-of-file and error indicators are reset only when you open the file or
explicitly call the clearerr, edfseek, fseek, or rewind function.
Example
This example resets the end-of-file and error indicators for the file $a.b.c:
#include <stdioh>
FILE *fp;
fp = fopen("$a.b.c", "r+");
/* ... */
clearerr(fp);
#include <stdioh>
void clearerr(FILE *stream);
