radixsort
RADIXSORT(3) BSD Library Functions Manual RADIXSORT(3)
NAME
radixsort, sradixsort -- radix sort
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <limits.h>
#include <stdlib.h>
int
radixsort(const unsigned char **base, int nmemb, const unsigned char *table, unsigned endbyte);
int
sradixsort(const unsigned char **base, int nmemb, const unsigned char *table, unsigned endbyte);
DESCRIPTION
The radixsort() and sradixsort() functions are implementations of radix sort.
These functions sort an array of pointers to byte strings, the initial member of which is referenced by base. The byte strings may contain
any values; the end of each string is denoted by the user-specified value endbyte.
Applications may specify a sort order by providing the table argument. If non-NULL, table must reference an array of UCHAR_MAX + 1 bytes
which contains the sort weight of each possible byte value. The end-of-string byte must have a sort weight of 0 or 255 (for sorting in
reverse order). More than one byte may have the same sort weight. The table argument is useful for applications which wish to sort differ-
ent characters equally, for example, providing a table with the same weights for A-Z as for a-z will result in a case-insensitive sort. If
table is NULL, the contents of the array are sorted in ascending order according to the ASCII order of the byte strings they reference and
endbyte has a sorting weight of 0.
The sradixsort() function is stable, that is, if two elements compare as equal, their order in the sorted array is unchanged. The
sradixsort() function uses additional memory sufficient to hold nmemb pointers.
The radixsort() function is not stable, but uses no additional memory.
These functions are variants of most-significant-byte radix sorting; in particular, see D.E. Knuth's Algorithm R and section 5.2.5, exercise
10. They take linear time relative to the number of bytes in the strings.
RETURN VALUES
The radixsort() function returns the value 0 if successful; otherwise the value -1 is returned and the global variable errno is set to indi-
cate the error.
ERRORS
[EINVAL] The value of the endbyte element of table is not 0 or 255.
Additionally, the sradixsort() function may fail and set errno for any of the errors specified for the library routine malloc(3).
