File
Handling Functions
Most of the high level input/output
functions which deal with files are easily recognizable in that they start with
the letter `f'. Some of these functions will appear strikingly familiar. For
instance:
fprintf()
fscanf()
fgets()
fputs()
These are all generalized file
handling versions of the standard input/output library. They work with
generalized files, as opposed to the specific files stdin and stdout which printf() and scanf() use. The file versions differ only in that they need an
extra piece of information: the file pointer to a particular portal. This is
passed as an extra parameter to the functions. they process data in an
identical way to their standard I/O counterparts. Other filing functions will
not look so familiar. For example:
fopen()
fclose()
getc()
ungetc();
putc()
fgetc()
fputc()
feof()
