pipe function

+ +

+pipe creates two file descriptors which can be used by +parent and child processes to communicate data. A child process can +be created with the fork function. +

+ + + + + +

+
+	Library:   unistd.h
+
+	Prototype: int pipe(int fd[2]);
+
+	Syntax:    int fd[2];
+		   pipe(fd);
+

+ +

+On error, pipe returns -1.

+Once the pipe has been executed, the data can be transfered +using read and +write. +

Notes:

+Make sure that when you read +exactly the same number of bytes that are +written! I spend HOURS +trying to figure out why I was loosing data because of this feature!! +

Examples:

+ +

+ read and write fixed length records. +

+ + + read and write variable length records. + +
