- FREAD(3) Minix Programmer's Manual FREAD(3)
- NAME
- fread, fwrite - buffered binary input/output
- SYNOPSIS
- #include <sys/types.h>
- #include <stdio.h>
- size_t fread(void *ptr, size_t itemsize, size_t nitems, FILE *stream)
- size_t fwrite(void *ptr, size_t itemsize, size_t nitems, FILE *stream)
- DESCRIPTION
- Fread reads, into a block beginning at ptr, nitems of data of the type of
- *ptr from the named input stream. It returns the number of items
- actually read.
- If stream is stdin and the standard output is line buffered, then any
- partial output line will be flushed before any call to read(2) to satisfy
- the fread.
- Fwrite appends at most nitems of data of the type of *ptr beginning at
- ptr to the named output stream. It returns the number of items actually
- written.
- SEE ALSO
- read(2), write(2), fopen(3), getc(3), putc(3), gets(3), puts(3),
- printf(3), scanf(3).
- DIAGNOSTICS
- Fread and fwrite return 0 upon end of file or error.
