18 | SYNOPSIS |
---|
19 | #include <string.h> |
---|
20 | char *strerror(int <[errnum]>); |
---|
21 | char *strerror_l(int <[errnum]>, locale_t <[locale]>); |
---|
22 | char *_strerror_r(struct _reent <[ptr]>, int <[errnum]>, |
---|
23 | int <[internal]>, int *<[error]>); |
---|
24 | |
---|
25 | DESCRIPTION |
---|
26 | <<strerror>> converts the error number <[errnum]> into a |
---|
27 | string. The value of <[errnum]> is usually a copy of <<errno>>. |
---|
28 | If <<errnum>> is not a known error number, the result points to an |
---|
29 | empty string. |
---|
30 | |
---|
31 | <<strerror_l>> is like <<strerror>> but creates a string in a format |
---|
32 | as expected in locale <[locale]>. If <[locale]> is LC_GLOBAL_LOCALE or |
---|
33 | not a valid locale object, the behaviour is undefined. |
---|
34 | |
---|
35 | This implementation of <<strerror>> prints out the following strings |
---|
36 | for each of the values defined in `<<errno.h>>': |
---|
37 | |
---|
38 | o+ |

326 | <<_strerror_r>> is a reentrant version of the above. |
---|
327 | |
---|
328 | RETURNS |
---|
329 | This function returns a pointer to a string. Your application must |
---|
330 | not modify that string. |
---|
331 | |
---|
332 | PORTABILITY |
---|
333 | ANSI C requires <<strerror>>, but does not specify the strings used |
---|
334 | for each error number. |
---|
335 | |
---|
336 | <<strerror_l>> is POSIX-1.2008. |
---|
337 | |
---|
338 | Although this implementation of <<strerror>> is reentrant (depending |
---|
339 | on <<_user_strerror>>), ANSI C declares that subsequent calls to |
---|
340 | <<strerror>> may overwrite the result string; therefore portable |
---|
341 | code cannot depend on the reentrancy of this subroutine. |
---|
342 | |
---|
343 | Although this implementation of <<strerror>> guarantees a non-null |
---|
344 | result with a NUL-terminator, some implementations return <<NULL>> |
---|
345 | on failure. Although POSIX allows <<strerror>> to set <<errno>> |
---|
346 | to EINVAL on failure, this implementation does not do so (unless |
---|
347 | you provide <<_user_strerror>>). |
---|
348 | |
---|
349 | POSIX recommends that unknown <[errnum]> result in a message |
---|
350 | including that value, however it is not a requirement and this |
---|
351 | implementation does not provide that information (unless you |
---|
352 | provide <<_user_strerror>>). |
---|
353 | |
---|
354 | This implementation of <<strerror>> provides for user-defined |
---|
355 | extensibility. <<errno.h>> defines <[__ELASTERROR]>, which can be |
---|
356 | used as a base for user-defined error values. If the user supplies a |
---|
357 | routine named <<_user_strerror>>, and <[errnum]> passed to |
---|
358 | <<strerror>> does not match any of the supported values, |
---|
359 | <<_user_strerror>> is called with three arguments. The first is of |
---|
360 | type <[int]>, and is the <[errnum]> value unknown to <<strerror>>. |
---|
361 | The second is of type <[int]>, and matches the <[internal]> argument |
---|
362 | of <<_strerror_r>>; this should be zero if called from <<strerror>> |
---|
363 | and non-zero if called from any other function; <<_user_strerror>> can |
---|
364 | use this information to satisfy the POSIX rule that no other |
---|
365 | standardized function can overwrite a static buffer reused by |
---|
366 | <<strerror>>. The third is of type <[int *]>, and matches the |
---|
367 | <[error]> argument of <<_strerror_r>>; if a non-zero value is stored |
---|
368 | into that location (usually <[EINVAL]>), then <<strerror>> will set |
---|
369 | <<errno>> to that value, and the XPG variant of <<strerror_r>> will |
---|
370 | return that value instead of zero or <[ERANGE]>. <<_user_strerror>> |
---|
371 | returns a <[char *]> value; returning <[NULL]> implies that the user |
---|
372 | function did not choose to handle <[errnum]>. The default |
---|
373 | <<_user_strerror>> returns <[NULL]> for all input values. Note that |
---|
374 | <<_user_sterror>> must be thread-safe, and only denote errors via the |
---|
375 | third argument rather than modifying <<errno>>, if <<strerror>> and |
---|
376 | <<strerror_r>> are are to comply with POSIX. |
---|
377 | |
---|
378 | <<strerror>> requires no supporting OS subroutines. |
