Retorna o nmero de bytes na pgina. Este  o tamanho da pgina do sistema,
o qual no  necessariamente o mesmo do tamanho da pgina do hardware.
.SH NOTAS
.B getpagesize
 implementado como um biblioteca de funo no formato DLL 4.4.1. Dependendo de como 
definida quando a biblioteca  compilada, esta funo retorna
.B EXEC_PAGESIZE
(seleciona 4096 no Linux 0.99.11),
.B NBPG
(seleciona to 4096 no Linux 0.99.11), ou
.B NBPC
(no  definida no Linux 0.99.11 ou na bibliotecas DLL 4.4.1).
.SH PROBLEMAS
Dependendo da arquitetura e verso da bibliotecas, esta biblioteca pode
chamar uma chamada de sistema ou no. Ela pode retornar um volor diferente
a partir daquela da chamada de sistema. Por exemplo, no sun4 com libc5
esta rotina retorna EXEC_PAGESIZE, o qual  8192, e no
PAGE_SIZE, o qual  4096, ou o resultado da chamada de sistema,
que tambm  4096.
