qsort

qsort(3)						     Library Functions Manual							  qsort(3)

NAME

       qsort - Sorts a table in place

LIBRARY

       Standard C Library (libc.so, libc.a)

SYNOPSIS

       #include <stdlib.h>

       void qsort(
	       void *base,
	       size_t nmemb,
	       size_t size,
	       int (*compar) (const void *, const void *));

STANDARDS

       Interfaces documented on this reference page conform to industry standards as follows:

       qsort():  XPG4, XPG4-UNIX

       Refer to the standards(5) reference page for more information about industry standards and associated tags.

PARAMETERS

       Points  to  the	first entry in the table.  Specifies the number of entries in the table.  Specifies the size in bytes of each table entry.
       Points to the user-specified function to be used to compare pairs of table elements.  The comparison  function  will  be  called  with  two
       parameters  that  point	to the two elements to be compared. The comparison function must return an integer less than, equal to, or greater
       than zero, depending on whether the first element in the comparison is considered less than, equal to, or greater than the second element.

DESCRIPTION

       The qsort() function sorts a table having a specified number of entries. The contents of the table are sorted in ascending order  according
       to a user-specified comparison function (the strcmp() function, for example).

NOTES

       The  comparison	function  need	not compare every byte, so arbitrary data may be contained in the elements in addition to the values being
       compared.

       When two members compare equal, their order in the sorted array is indeterminate.
