| 16 | .SH DESCRIPTION |
| 17 | .B getln |
| 18 | reads a line of characters, terminated by a |
| 19 | .I sep |
| 20 | character, |
| 21 | from |
| 22 | .IR ss . |
| 23 | It returns the line in |
| 24 | .I sa |
| 25 | and sets |
| 26 | .I match |
| 27 | to 1. |
| 28 | |
| 29 | If |
| 30 | .B getln |
| 31 | sees end-of-input before it sees |
| 32 | .IR sep , |
| 33 | it returns the partial line in |
| 34 | .I sa |
| 35 | and sets |
| 36 | .I match |
| 37 | to 0. |
| 38 | |
| 39 | .B getln |
| 40 | normally returns 0. |
| 41 | If it runs out of memory, |
| 42 | or encounters an error from |
| 43 | .IR ss , |
| 44 | it returns -1, |
| 45 | setting |
| 46 | .B errno |
| 47 | appropriately. |
