intcmp(constvoid* A,constvoid* B){return(*(structnode*)A).num - (*(structnode*)B).num ; } 取一个结构体的数据大小时可以用sizeof(a[0]) 参考资料: https://www.runoob.com/cprogramming/c-function-qsort.html https://blog.csdn.net/qq_43749739/article/details/87381277...
The qsort() function sorts an array ofnumelements, each ofwidthbytes in size, where the first element of the array is pointed to bybase. Thecomparepointer points to a function, which you supply, that compares two array elements and returns an integer value specifying their relationship. The ...
I wrote a qsort string comparision function a while back for BRL-CAD, here is the compare function used(keep in mind written in C, could be optimized). * Sort function called by quick sort to sort data according * to its second field in the string */ int sort(const void* a, const...
