No additional characters are read after a new-line character (which is retained) or after end-of-file. A null character is written immediately after the last character read into the array. .PP The .I fgets function returns .I s if successful. If end-of-file is encountered and no characters have been read into the array, the contents of the array remain unchanged and a null pointer is returned. If a read error occurs during the operation, the array contents are indeterminate and a null pointer is returned. .SH "SEE ALSO" getc(3), ferror(3) fread(3), scanf(3) .SH STANDARDS The .I fgets function is ANSI C compatible.
