11 | SYNOPSIS |
---|
12 | #include <ctype.h> |
---|
13 | int toascii(int <[c]>); |
---|
14 | |
---|
15 | #include <ctype.h> |
---|
16 | int toascii_l(int <[c]>, locale_t <[locale]>); |
---|

---|
18 | DESCRIPTION |
---|
19 | <<toascii>> is a macro which coerces integers to the ASCII range (0--127) by zeroing any higher-order bits. |
---|
20 | |
---|
21 | <<toascii_l>> is like <<toascii>> but performs the function based on the |
---|
22 | locale specified by the locale object locale. If <[locale]> is |
---|
23 | LC_GLOBAL_LOCALE or not a valid locale object, the behaviour is undefined. |
---|
24 | |
---|
25 | You can use a compiled subroutine instead of the macro definition by |
---|
26 | undefining this macro using `<<#undef toascii>>' or `<<#undef toascii_l>>'. |
---|
27 | |
---|
28 | RETURNS |
---|
29 | <<toascii>>, <<toascii_l>> return integers between 0 and 127. |
---|
30 | |
---|
31 | PORTABILITY |
---|
32 | <<toascii>> is X/Open, BSD and POSIX-1.2001, but marked obsolete in |
---|
33 | POSIX-1.2008. |
---|
34 | <<toascii_l>> is a GNU extension. |
---|
35 | |
---|
36 | No supporting OS subroutines are required. |
