PN67567: FSANF LIBRARY FUNCTION ENTERS INTO A INFINITE LOOP WHEN EOF IS USED AS THE TEST FOR A WHILE LOOP.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• The fsanf function does not set the EOF flag when scanning
  numeric data. If a program codes a conditional call to
  fsanf, and uses the !=EOF as the test, the loop will not end.
  The fsanf logic will only set the EOF flag for numeric data
  if a conversion error is encountered, or an I/O error occurs.
  The fsanf function will not set the EOF flag if that last record
  is reached. If the FEOF is used in the while loop, then the
  loop will end on the last record.

Problem summary

• ****************************************************************
  * USERS AFFECTED: Users who use fscanf()/scanf() after eof is  *
  *                 reached or expect fscanf()/scanf() to report *
  *                 when eof is passed.                          *
  ****************************************************************
  * PROBLEM DESCRIPTION: The EOF return code is not returned     *
  *                      when scanf()/fscanf() is called and     *
  *                      position is already at eof.             *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  fscanf()/scanf() returns 0 instead of EOF when called and
  position is already at eof.
