[英]c pthread passing array of type int
I am passing an array of type int pthread_create and getting error: 我正在传递一个类型为pthread_create int的数组并收到错误:
histogram.c:138:3: warning: passing argument 3 of
‘pthread_create’ from incompatible pointer type [enabled by default]
expected ‘void * (*)(void *)’ but argument is of type ‘void * (*)(int *)’
void *output_results();
pthread_create(&t2, NULL, output_results, (void *)bins);
void *output_results(int *bins) {
some code
}
Should be 应该
void *output_results(void*);
pthread_create(&t2, NULL, output_results, (void *)bins);
void *output_results(void *data) {
int *bins = (int*)data;
// some code
}
The error message is pretty clear: the function should be of type void * (*)(void *)
and not void * (*)(int *)
(plus your prototype for output_results
was not matching its definition). 错误消息非常清楚:该函数的类型应该为
void * (*)(void *)
而不是void * (*)(int *)
(加上output_results
的原型与它的定义不匹配)。
The compilation error is because pthread_create
expects void *output_results(void *bins)
, but you have int *bins
. 编译错误是因为
pthread_create
预期为void *output_results(void *bins)
,但是您有int *bins
。
Also, the declaration of output_results
you're using does not match its definition. 另外,您使用的
output_results
声明与其定义不匹配。
