.SH DESCRIPCIÓN
La función \fBqsort()\fP ordena un vector de \fInmiemb\fP elementos de
tamaño \fItam\fP.  El argumento \fIbase\fP apunta al comienzo del vector.
.PP
Los contenidos del vector se clasifican en orden ascendente de acuerdo
a una función de comparación a la que apunta \fIcompar\fP, que se
llama con dos argumentos que apuntan a los objetos a comparar.
.PP
La función de comparación debe devolver un entero menor que, igual a,
o mayor que cero si el primer argumento se considera respectivamente
menor, igual o mayor que el segundo. Si dos miembros se comparan como
iguales, su orden en el vector clasificado queda indefinido.
.SH "VALOR DEVUELTO"
La función \fBqsort()\fP no devuelve nada.
