umask \- establece la mscara de creacin de ficheros
.SH SINOPSIS
.B #include <sys/stat.h>
.sp
.BI "int umask(int " mask );
.SH DESCRIPCIN
.B umask
establece la mscara de usuario a
.I mask
& 0777.
La mscara de usuario es usada por
.BR open (2)
para establecer los permisos iniciales de un fichero recin creado.
Especficamente, los permisos presentes en la mscara se desactivan a partir de
0666 (as pues, por ejemplo, el valor comn por defecto de umask, 022,
provoca que los nuevos ficheros se creen con permisos 0666 & ~022 = 0755 =
rw-r--r--).
.SH "VALOR DEVUELTO"
Esta llamada al sistema siempre tiene xito y devuelve el valor anterior de la
mscara.
.SH "CONFORME A"
SVr4, SVID, POSIX, X/OPEN, BSD 4.3
