gets#

Synopsis#

#include <stdio.h>

char *gets(char *s);

Status#

Partially implemented

Conformance#

IEEE Std 1003.1-2017

Description#

The purpose is to get a string from a stdin stream. The gets() function shall read bytes from the standard input stream, stdin, into the array pointed to by s, until a <newline> is read or an end-of-file condition is encountered. Any <newline> shall be discarded and a null byte shall be placed immediately after the last byte read into the array.

The gets() function may mark the last data access timestamp of the file associated with stream for update. The last data access timestamp shall be marked for update by the first successful execution of fgetc(), fgets(), fread(), fscanf(), getc(), getchar(), getdelim(), getline(), gets(), or scanf() using stream that returns data not supplied by a prior call to ungetc().

Return value#

Upon successful completion, gets() shall return s. If the end-of-file indicator for the stream is set, or if the stream is at end-of-file, the end-of-file indicator for the stream shall be set and gets() shall return a null pointer. If a read error occurs, the error indicator for the stream shall be set, gets() shall return a null pointer, and set errno to indicate the error.

Errors#

Refer to fgetc.
