如何使Android的glob.c工作？

glob.c無法識別的應用程序目錄的目錄：如何使Android的glob.c工作？

const char* cpath = env->GetStringUTFChars(jpath, 0); 
debug("testing converting for [%s]", cpath); 

// 
const char *patnext = cpath; 
size_t limit; 
wchar_t *bufnext, *bufend, patbuf[MAXPATHLEN]; 
mbstate_t mbs; 
wchar_t wc; 
size_t clen; 

bufnext = patbuf; 
bufend = bufnext + MAXPATHLEN - 1; 

int len = 0; 
while (bufend - bufnext >= MB_CUR_MAX) { 
    clen = mbrtowc(&wc, patnext, MB_LEN_MAX, &mbs); 

    debug("clen = %i", clen); 

    if (clen == (size_t)-1 || clen == (size_t)-2) { 
     env->ReleaseStringUTFChars(jpath, cpath); 
     return JNI_FALSE; 
    } 
    else if (clen == 0) 
     break; 

    *bufnext++ = wc; 
    patnext += clen; 
    len += clen; 
} 
for (int i=0; i<len; i++) { 
    debug("%c", patbuf[i]); 
} 
glob((const char *)patbuf, GLOB_MARK, NULL, &glob_results); 
debug("glob returned %i\n", glob_results.gl_pathc);

返回0，但1的預期。在Github上

怎樣纔可以解決嗎？任何走動？

你從哪裏找到glob.c和glob.h？你提到的github路徑不再存在。你解決了你的問題嗎？ –

您的patbuf緩衝區是wchar_t項目的數組，您不能簡單地將其地址類型轉換爲'const char *'。 glob（）期望傳遞一個真正的8位字符串的地址（例如一個UTF-8）。

此外，你永遠不會零終止你的patbuf緩衝區，這本身就是另一個嚴重的錯誤。

您應該將路徑轉換爲零終止的UTF-8字符串，並將其地址傳遞給glob（）。

希望這會有所幫助。

patbuf是wchar_t，所以我相信它是UTF-8字符串。看問題更新：添加代碼。您可以在問題 – 4ntoine

的鏈接中看到完整的應用程序和本機代碼。否，wchar_t緩衝區不能用於保存UTF-8字符串。您應該嘗試閱讀有關Unicode代碼點及其各種編碼（UTF-8，UTF-16和Java的經過修改的UTF-8）以瞭解發生了什麼。解決您的問題的方法是將env-> GetStringUTFChars（）的結果直接傳遞給glob（）。之後不要忘記調用env-> ReleaseStringUTFChars（）。 – Digit
