| 21 | .SH DESCRIPTION | |
| 22 | .I Gets | |
| 23 | reads a string into | |
| 24 | .I s | |
| 25 | from the standard input stream | |
| 26 | .B stdin. | |
| 27 | The string is terminated by a newline | |
| 28 | character, which is replaced in | |
| 29 | .I s | |
| 30 | by a null character. | |
| 31 | .I Gets | |
| 32 | returns its argument. | |
| 33 | .PP | |
| 34 | .I Fgets | |
| 35 | reads | |
| 36 | .IR n \-1 | |
| 37 | characters, or up to a newline | |
| 38 | character, whichever comes first, | |
| 39 | from the | |
| 40 | .I stream | |
| 41 | into the string | |
| 42 | .IR s . | |
| 43 | The last character read into | |
| 44 | .I s | |
| 45 | is followed by a null character. | |
| 46 | .I Fgets | |
| 47 | returns its first argument. | |

| 52 | .SH DIAGNOSTICS | |
| 53 | .I Gets | |
| 54 | and | |
| 55 | .I fgets | |
| 56 | return the constant pointer | |
| 57 | .SM | |
| 58 | .B NULL | |
| 59 | upon end of file or error. | |
| 60 | .SH BUGS | |
| 61 | .I Gets | |
| 62 | deletes a newline, | |
| 63 | .I fgets | |
| 64 | keeps it, | |
| 65 | all in the name of backward compatibility. |
