[英]Conflicting types for 'function' and implicit declaration of function 'function' is invalid in C99
[英]How to fix these error “Implicit declaration of function is invalid in C99” and “Conflicting types” in .c file in Xcode objective-C?
Actually iam importing.C file library in objective-c.I have fixed most of errors.but below two errors iam not able to resolve.. The first one is: "Implicit declaration of function 'read_binary_profile' is invalid in C99"
第二個是:“'read_binary_profile' 的沖突類型”
你能幫忙解決這個問題嗎?
下面是代碼

通過聲明方法解決該錯誤后,它顯示以下錯誤

“函數的隱式聲明”意味着當您調用 function 時,編譯器看不到 function 聲明。 自 C99 標准以來,C 不再允許這樣做。
顯然,在面對這樣的 function 調用時,您的編譯器仍會嘗試從中生成舊的 C90“隱式 int”,這意味着在發現此p=my_read_binary_profile(b_profile,0)
時,它將把 function 視為聲明為int my_read_binary_profile (int, int)
並相應地生成機器碼,這顯然是錯誤的。
這給出了第二個錯誤,“隱式 int”廢話與正確的 function 定義vcp_profile_t * my_read_binary_profile(void *pmem, int allocate)
不匹配,因此類型沖突。
通過在文件頂部添加 function 聲明原型來解決此問題:
vcp_profile_t* my_read_binary_profile(void* pmem, int allocate);
