在 cuda 中添加 char 数组 [英] Add char arrays in cuda
问题描述
我正在尝试在 cuda 中添加 2 个字符数组,但没有任何效果.我尝试使用:
I am trying to add 2 char arrays in cuda, but nothing is working. I tried to use:
char temp[32];
strcpy(temp, my_array);
strcat(temp, my_array_2);
当我在内核中使用它时 - 我收到 error : Calling a __host__ function("strcpy") from a __global__ function("Process") is not allowed
When I used this in kernel - I am getting error : calling a __host__ function("strcpy") from a __global__ function("Process") is not allowed
在此之后,我尝试在主机中使用这些函数,而不是在内核中 - 没有错误,但添加后我得到了奇怪的符号,如 ĶĶĶĶĶĶĶĶĶĶĶĶĶĶĶĶĶĶĶĶĶĶĶĶĶĶĶĶĶĶĶĶĶĶĶĶĶĶĶĶ
.
After this, I tried to use these functions in host, not in kernel - no error,but after addition I am getting strange symbols like ĶĶĶĶĶĶĶĶĶĶĶĶĶĶĶĶĶĶĶĶĶĶĶĶĶĶĶĶĶĶĶĶ
.
那么,如何在 CUDA
中添加两个(或更多)字符数组?
So, how I can add two ( or more ) char arrays in CUDA
?

编写你自己的函数:
__device__ char * my_strcpy(char *dest, const char *src){
int i = 0;
do {
dest[i] = src[i];}
while (src[i++] != 0);
return dest;
}
__device__ char * my_strcat(char *dest, const char *src){
int i = 0;
while (dest[i] != 0) i++;
my_strcpy(dest+i, src);
return dest;
}
当我们这样做时,这里是strcmp
