The child thread loops 10 times, then the main thread loops 100 times, then goes back to the child thread loop 10 times, then goes back to the main thread and loops 100 times, so Loop 50 times, try to write the code.#include #include#includestring.h>

Translated from: http://blog.chinaunix.net/uid-27105712-id-3270102.htmlIn Linux development, there are several things related to performance, technical staff are very concerned about: process, cpu,mem, network io, disk IO. This paper intends to be

1. File WriteAppend method:void Appendwt () {FILE *pfile = fopen ("Data.txt", "ab+");//Use "ab+" each time to insert to the last face, call Fseek also useless char *str= "hello,world!45% 13ad2014/23/13add\n "; Fwrite (Str,1,strlen (str), pFile);

Theoretical basis Stream: Call fopen Open file after file read and write operation will create a stream, socket network communication will also create a flow, the flow is a data transmission for the purpose of a bridge, in fact, refers to

Char *fputs (char *s, int n, FILE *fp)int fputs (char *s, FILE *FP)Fgets returns the first address of the read string, an error or the end of the file, and returns null when normal.Fputs returns the last character written when normal, and an error

C/C ++ does not have a standard logstore, which is directly replaced by printf. However, it does not support hierarchical control of output information. It seems too important to use log4cpp. Here I will give a few simple log functions that I often

File stream File streams can be written as text streams. Data is written as characters and these characters are organized as data rows. Each row ends with a line break, data such as int or double must be converted to characters before being written
