gets, fgets - get a string from a stream
char *gets(char *s);
char *fgets(char *s, int n, FILE *stream);
The gets() function reads bytes from the standard input
stream (see intro(3)), stdin, into the array pointed to by
s, until a newline character is read or an end-of-file con-
dition is encountered. The newline character is discarded
and the string is terminated with a null byte.
If the length of an input line exceeds the size of s,
indeterminate behavior may result. For this reason, it is
strongly recommended that gets() be avoided in favor of
The fgets() function reads bytes from the stream into the
array pointed to by s, until n-1 bytes are read, or a new-
line character is read and transferred to s, or an end-of-
file condition is encountered. The string is then terminated
with a null byte.
The fgets() function may mark the st_atime field of the file
associated with stream for update. The st_atime field will
be marked for update by the first successful execution of
fgetc(3C), fgets(), fgetwc(3C), fgetws(3C), fread(3C),
fscanf(3C), getc(3C), getchar(3C), gets(), or scanf(3C)
using stream that returns data not supplied by a prior call
to ungetc(3C) or ungetwc(3C).
If end-of-file is encountered and no bytes have been read,
no bytes are transferred to s and a null pointer is
returned. If a read error occurs, such as trying to use
these functions on a file that has not been opened for read-
ing, a null pointer is returned and the error indicator for
the stream is set. If end-of-file is encountered, the EOF
indicator for the stream is set. Otherwise s is returned.
Refer to fgetc(3C).
