gets()

Arguments:

buf

A buffer where the function can store the string.

Library:

libc

Use the -l c option to qcc to link against this library. This library is usually included automatically.

Description:

The gets() function gets a string of characters from the stdin stream, and stores them in the array pointed to by buf until end-of-file is encountered or a newline character is read. Any newline character is discarded, and the string is NUL-terminated.

The gets() function is similar to fgets(), except that gets() operates with stdin, has no size argument, and replaces a newline character with the NUL character.

Returns:

• If successful, gets() returns buf.
• If the end-of-file indictor for the stream is set, or the stream is at the end of the file, gets() sets the end-of-file indicator and returns NULL.
• If an error occurred, gets() sets the error indicator, sets errno, and returns NULL.

Examples:

#include <stdio.h>
#include <stdlib.h>

int main( void )
{
    char buffer[80];

    while( gets( buffer ) != NULL ) {
        puts( buffer );
    }
    
    return EXIT_SUCCESS;
}

Classification:

ANSI, POSIX 1003.1 OB. This function is marked as obsolescent, and may be removed from a future version of the POSIX standard. It's already been removed from C11.
