The ifx_gl_lc_errno() function
The ifx_gl_lc_errno() function returns the value of the error number that some other function has set.
Syntax
#include <gls.h>
...
int ifx_gl_lc_errno(void);| Valid in client application | Valid in DataBlade® UDR |
|---|---|
| Yes | Yes |
Usage
The functions set the error number, of type int, to indicate additional information about an error that occurred. functions set this value only when an error occurs (unless documented otherwise). Because any function can set the error number, you must use ifx_gl_lc_errno() to inspect the error number immediately after you call the function in which the error occurred.
Tip: The Errors section for
each function documents the values that ifx_gl_lc_errno() returns
after that particular function.
Certain code-set conversion functions are not dependent on a locale and do not set an error number that you can retrieve with ifx_gl_lc_errno(). Instead, these functions return a negative error code.
Return values
- Integer error number
- The error number that the function has set. These error numbers are defined in the gls.h file and are described in the Errors section for each function.
- -1
- The function was not successful. The current processing locale has not been correctly initialized.
Errors
None
