NAME
freelocale -- free resources allocated for a locale object
SYNOPSIS
#include <locale.h>
void freelocale(locale_t locobj);
DESCRIPTION
The freelocale() function shall cause the resources allocated for a locale object returned by a call to the newlocale() or duplocale()
functions to be released.
The behavior is undefined if the locobj argument is the special locale object LC_GLOBAL_LOCALE or is not a valid locale object handle.
Any use of a locale object that has been freed results in undefined behavior.
RETURN VALUE
None.
ERRORS
None.
The following sections are informative.
EXAMPLES
Freeing Up a Locale Object
The following example shows a code fragment to free a locale object created by newlocale():
#include <locale.h>
...
/* Every locale object allocated with newlocale() should be
* freed using freelocale():
*/
locale_t loc;
/* Get the locale. */
loc = newlocale (LC_CTYPE_MASK | LC_TIME_MASK, "locname", NULL);
/* ... Use the locale object ... */
...
/* Free the locale object resources. */
freelocale (loc);
APPLICATION USAGE
None.
RATIONALE
None.
FUTURE DIRECTIONS
None.

NAME
isblank, isblank_l -- test for a blank character
SYNOPSIS
#include <ctype.h>
int isblank(int c);
int isblank_l(int c, locale_t locale);
DESCRIPTION
For isblank(): The functionality described on this reference page is aligned with the ISO C standard. Any conflict between the requirements
described here and the ISO C standard is unintentional. This volume of POSIX.1-2008 defers to the ISO C standard.
The isblank() and isblank_l() functions shall test whether c is a character of class blank in the current locale, or in the locale repre-
sented by locale, respectively; see the Base Definitions volume of POSIX.1-2008, Chapter 7, Locale.
The c argument is a type int, the value of which the application shall ensure is a character representable as an unsigned char or equal to
the value of the macro EOF. If the argument has any other value, the behavior is undefined.
The behavior is undefined if the locale argument to isblank_l() is the special locale object LC_GLOBAL_LOCALE or is not a valid locale
object handle.
RETURN VALUE
The isblank() and isblank_l() functions shall return non-zero if c is a <blank>; otherwise, they shall return 0.
ERRORS
No errors are defined.
The following sections are informative.
EXAMPLES
None.
APPLICATION USAGE
To ensure applications portability, especially across natural languages, only these functions and the functions in the reference pages
listed in the SEE ALSO section should be used for character classification.
RATIONALE
None.
FUTURE DIRECTIONS
None.
