 NAME

fgets - get a string from a stream

 SYNOPSIS



#include <stdio.h>

char *fgets(char *s, int n, FILE *stream);

 DESCRIPTION

The fgets() function reads bytes from stream into the array pointed to by s, until n-1 bytes are read, or a newline 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(), fgets(), fgetwc(), fgetws(), fread(), fscanf(), getc(), getchar(), gets() or scanf() using stream that returns data not supplied by a prior call to ungetc() or ungetwc().

 RETURN VALUE

Upon successful completion, fgets() returns s. If the stream is at end-of-file, the end-of-file indicator for the stream is set and fgets() returns a null pointer. If a read error occurs, the error indicator for the stream is set, fgets() returns a null pointer and sets errno to indicate the error.

 ERRORS

Refer to fgetc().
