String operations

The HCL Informix® GLS library supports string traversal and string processing operations on multibyte-character and wide-character strings.

String traversal
Because a single-byte character occupies only one byte, string traversal of a single-byte character string can use the built-in scaling of the C compiler. However, you must take special steps to handle string traversal of multibyte-character and wide-character strings.
String processing
The HCL Informix GLS library provides functions for concatenation, string copying, string-length determination, and character searching. The Informix GLS library provides both multibyte and wide-character functions for these string-processing tasks.
Character/string comparison and sorting
Collation involves the sorting of character data that is either stored in a database or manipulated in a client application.
