< c‎ | io

Defined in header <stdio.h>
char *fgets( char          *str, int count, FILE          *stream );
(until C99)
char *fgets( char *restrict str, int count, FILE *restrict stream );
(since C99)

Reads at most count - 1 characters from the given file stream and stores them in str. The produced character string is always NULL-terminated. Parsing stops if end-of-file occurs or a newline character is found, in which case str will contain that newline character.

[edit] Parameters

str - string to read the characters to
count - the length of str
stream - file stream to read the data from

[edit] Return value

str on success, NULL on failure.

If the failure has been caused by end of file condition, additionally sets the eof indicator (see feof()) on stream. If the failure has been caused by some other error, sets the error indicator (see ferror()) on stream.
