QSORT(3) UNIX Programmer's Manual QSORT(3) NAME qsort - quicker sort SYNOPSIS qsort(base, nel, width, compar) char *base; unsigned nel; int (*compar)( ); DESCRIPTION _Q_s_o_r_t is an implementation of the quicker-sort algorithm. The first argument is a pointer to the base of the data; the second is the number of elements; the third is the width of an element in bytes; the last is the name of the comparison routine to be called with two arguments which are pointers to the elements being compared. The routine must return an integer less than, equal to, or greater than 0 according as the first argument is to be considered less than, equal to, or greater than the second. BUGS Static variiables are used to store the comparison function and _w_i_d_t_h. This fails if the comparison function itself calls _q_s_o_r_t. SEE ALSO sort(1) Printed 7/30/83 1
