Returns the number of collation values for a given string.
include <string.h> int strncollen (String, Number) const char *String; const int Number;
The strncollen subroutine returns the number of collation values for a given string pointed to by the String parameter. The count of collation values is terminated when either a null character is encountered or when the number of bytes indicated by the Number parameter have been examined.
The collation values are set by the setlocale subroutine for the LC_COLLATE category. For example, if the locale is set to Es_ES (Spanish spoken in Spain) for the LC_COLLATE category, where `ch' has one collation value, then strncollen ('abchd', 5) returns 4.
In German, the ß (double s) character, has two collation values, so strncollen ('straßa', 6) returns 7.
If a character has no collation value, its collation length is 0.
| Number | The number of bytes in a string to be examined. |
| String | Pointer to a string to be examined for collation value. |
Upon successful completion, the strncollen subroutine returns the collation value for a given string, pointed to by the String parameter.
