.sp
.BI "size_t fread( void *" ptr ", size_t " size ", size_t " nmemb ,
.BI "FILE *" stream );
.sp
.BI "size_t fwrite( const void *" ptr ", size_t " size ", size_t " nmemb ,
.BI "FILE *" stream );
.SH DESCRIÇÃO
A função
.B fread
lê
.I nmemb
elementos de dados, cada um com
.I size
bytes, do fluxo apontado por
.IR stream ,
armazenando-os no local dado por
.IR ptr .
.PP
A função
.B fwrite
escreve
.I nmemb
elementos de dado, cada um com
.I size
bytes, no fluxo apontado por
.IR stream ,
obtendo-os a partir do local dado por
.IR ptr .
.SH "VALORES DE RETORNO"
.B fread
e
.B fwrite
retornam o número de itens lidos ou escritos com sucesso (isto é, não o número de 
caracteres). Se ocorre um erro, ou o fim do arquivo é atingido, o valor de retorno
é uma contagem curta de itens (ou zero).
.PP
.B fread
nãi distingue entre fim de arquivo e erro, e os chamadores precisam usar
.BR feof (3)
e
.BR ferror (3)
para determinar o que ocorreu.
.SH "VEJA TAMBÉM"
.BR feof "(3), "ferror "(3), " read "(2), " write (2)
.SH PADRÕES
As funções
.B fread
e
.B fwrite
estão em conformidade com ANSI X3.159-1989 (``ANSI C'').
