Description of Problem: fscanf does not return EOF if attempt to read fro 0 length file Version-Release number of selected component (if applicable): rpm 2.1.19-14 How Reproducible: Steps to Reproduce: 1. open file for writing, then close file 2. open file for read (filehandle != NULL) 3. fscanf(filehandle) returns 0 not EOF as expected Actual Results: returns 0 Expected Results: expect EOF Additional Information: on linux6.2 fscanf returns EOF feof(filehandle) is also wrong! I'm new to Linux but have experience in C
Can you come up with a testcase? It depends on what arguments fscanf gets.
Created attachment 34422 [details] source code that demonstrates EOF problem in fscanf
What glibc do you use? Under glibc-2.2.4-19 (which is the same source as 2.2.4-18.7.0, latest 7.0 errata), I get: fscanf result is -1, EOF value is -1
I performed the standard 7.0 installation. rpm shows glibc 2.1.92
glibc-2.2.4-19 fixes the problem! Thanks.
