Buenas, os cuento mi situación. En C existen librerías, o que te hacen la función de strlen para medir la longitud de esa string. Yo lo que he hecho es recrear esa función para utilizarla de e.

Because stuff is uninitialized before the call to strcpy.After the declaration stuff isn't an empty string, it is uninitialized data. strcat appends data to the end of a string - that is it finds the null terminator in the string and adds characters after that. An uninitialized string isn't gauranteed to have a null terminator so strcat is likely to crash. strcat, strncat - 二つの文字列を連結する. strlcat は glibc には存在せず、 POSIX による標準化もされていないが、 Linux では libbsd ライブラリ経由で利用できる。. linux中strcpy、memcpy的用法与区别 05-23 阅读数 2621. strcpy提供了字符串的复制,以 \0 为结束标志(即一旦遇到数据值为0的内存地址,拷贝过程即结束。函数原型如下:char strcpychar dest, const. strcat(连接两字符串) 表头文件. include 定义函数. char strcat char dest,const char src; 返回值. 返回参数dest的字符串起始地址.

Did you look up the function to find out what it is, and where it is supported? Looks like a C11 feature to me based on a quick Google search, and C11/C14 are based on C99. Remarks. The strcat_s function appends strSource to strDestination and terminates the resulting string with a null character. The initial character of strSource overwrites the terminating null character of strDestination.The behavior of strcat_s is undefined if the source and destination strings overlap. Note that the second parameter is the total size of the buffer, not the remaining size.

The strcpy_s function copies the contents in the address of src, including the terminating null character, to the location that's specified by dest. The destination string must be large enough to hold the source string and its terminating null character. The behavior of strcpy_s is undefined if the source and destination strings overlap. Copies the C string pointed by source into the array pointed by destination, including the terminating null character and stopping at that point. To avoid overflows, the size of the array pointed by destination shall be long enough to contain the same C string as source including the terminating null character, and should not overlap in memory with source. These functions all take a pointer to a mbstate_t object that the caller must maintain. This was originally intended to track shift states in the mb encodings, but modern ones such as UTF-8 do not need this. However these functions were designed on the assumption that the wc encoding is not a variable-width encoding and thus are designed to deal with exactly one wchar_t at a time, passing it.
