cuando hago un:
------------------
char *buffer;

buffer=(char *)malloc(sizeof(char) *TAMANYO)
-------------------

y luego un:
--------------------
a=read(fd, buffer,sizeof(buffer));
--------------------

a me devuelve -1 y no lee del fichero
�debo poner "read(fd,buffer,sizeof(buffer)*TAMANYO)"?
(el open del fichero (fd),  no me da problemas )

Mi intencion es leer de un fichero un bloque del tama�o que yo quiera y
colocarlo en el buffer;
