转载地址:https://blog.csdn.net/bdss58/article/details/78388858 在C语言中,有标准库limits.h定义了一些最大最小值常量,例如int类型的最大值常量INT_MAX,最小值常量INT_MIN,无符号整型uint类型的最大值常量UINT_MAX golang的标准库里没有定义这些变量。不过可以用位操作运算,轻松定义这些常量。 无符号整型uint...

Proposal Details I propose the addition of a function func MinNFunc[S ~[]E, E any](n int, x S, cmp func(a, b E) int) S which returns the n smallest elements of x in increasing order. If len(x) < n, then MinNFunc returns x sorted. MinNFun...

linux内核通过进程标识值(process identification value)-PID来标示进程,PID是一个数,类型位pid_t, 实际上就是int类型 为了与老版本的Unix或者Linux兼容,PID的最大值默认设置位32768(short int 短整型的最大值)。 查看 可以使用cat /proc/sys/kernel/pid_max来查看系统中可创建的进程数实际值 ...
