Sólo el súper-usuario puede especificar un incremento negativo, o sea, un aumento de la prioridad. .PP Observe que internamente, un número más alto es una prioridad más alta. No se confunda con el esquema de prioridad empleado por el programa \fBnice\fP. .SH "VALOR DEVUELTO" En caso de éxito, se devuelve cero. En caso de error, se devuelve \-1 y se pone un valor apropiado en \fIerrno\fP. .SH ERRORES .TP .B EPERM Un usuario normal intenta aumentar la prioridad, disminuyendo el valor numérico suministrando a la función un .IR inc negativo. .SH "CONFORME A" SVr4, SVID EXT, AT&T, X/OPEN, BSD 4.3. SVr4 documenta un código de error adicional EINVAL. .SH "VÉASE TAMBIÉN" .BR nice (1), .BR setpriority (2), .BR fork (2), .BR renice (8)
