Description
The function returns the next character from the named input stream.
The function is identical to (stdin).
The function behaves like but is a genuine function, not a macro. It may be used to save object text.
The function returns the next word (in a 32-bit integer on a VAX-11 or MIPS machine) from the named input stream. It returns the constant
EOF upon end of file or error, but since that is a good integer value, feof and should be used to check the success of The assumes no spe-
cial alignment in the file.
Restrictions
Because it is implemented as a macro, treats a stream argument with side effects incorrectly. In particular, `getc(*f++);' doesn't work as
expected.
Diagnostics
These functions return the integer constant EOF at end of file or upon read error.
A stop with message, `Reading bad file', means an attempt has been made to read from a stream that has not been opened for reading by
