Standard Streams - Standard Output (stdout)

Standard Output (stdout)

Standard output is the stream where a program writes its output data. The program requests data transfer with the write operation. Not all programs generate output. For example the file rename command (variously called mv, move, or ren) is silent on success.

Unless redirected, standard output is the text terminal which initiated the program.

The file descriptor for standard output is 1 (one); the POSIX definition is STDOUT_FILENO; the corresponding variable is FILE* stdout; similarly, the variable is std::cout.

Famous quotes containing the words standard and/or output:

    “Where shall we look for standard English but to the words of a standard man?”
    —Henry David Thoreau (1817–1862)

    “Lizzie Borden took an axe
    And gave her mother forty whacks;
    When she saw what she had done,
    She gave her father forty-one.”
    —Anonymous. Late 19th century ballad.

    The quatrain refers to the famous case of Lizzie Borden, tried for the murder of her father and stepmother on Aug. 4, 1892, in Fall River, Massachusetts. Though she was found innocent, there were many who contested the verdict, occasioning a prodigious output of articles and books, including, most recently, Frank Spiering’s Lizzie (1985)
