Function summary
This topic groups all the functions of the library by task.
Memory allocation

For more information, see Allocate memory.
Initialization and error handling
- The ifx_gl_init() function initializes the library.
For more information, see Initialize the library.
- The ifx_gl_lc_errno() function obtains the
value of the error

Stream input and output
The library provides the ifx_gl_getmb() and ifx_gl_putmb() functions to input and output multibyte characters in a user-defined location.
For more information, see Input and output streams.
Character processing
Most of the functions provide support for character processing of both multibyte and wide characters. This section lists the character-processing tasks and the functions that support them. For general information about character processing, see Character processing.

Character/string comparison and sorting
The library provides the ifx_gl_mbscoll() and ifx_gl_wcscoll() functions to obtain locale-specific order for characters and strings.
For general information, see Character/string comparison and sorting.
Data formatting
The library provides functions to support the conversion and formatting of locale-specific strings. This section lists the data types that involve locale-specific strings and the functions that support them. For general information about data formatting, see Data formatting.
Date and time conversion and formatting functions
