| Description |
I was surprised to find that there is no $feof system function to test for end-of-file on a file descriptor. This is in a similar category to the existing $ferror. In C, I suspect that feof() is used more often than ferror(). However, it could be argued that there is a workaround by calling $fgetc and then calling $ungetc to put the character back if it wasn't EOF. |
| Fix |
PROPOSAL revised and passed by BTF: ADD to list of File I/O tasks in introduction of section 17: $feof ADD new section: 17.2.8 Detecting end of file integer code; code = $feof ( fd ); Returns a non-zero value when EOF has previously been detected reading the input file fd. Returns zero otherwise. ADD correct bolding to this new section. CHANGE following section numbers to accomodate the new section. |
