| 18 | .SH DESCRIPTION | ||
| 19 | .B getln2 | ||
| 20 | reads a line of characters, terminated by a | ||
| 21 | .I sep | ||
| 22 | character, | ||
| 23 | from | ||
| 24 | .IR ss . | ||
| 25 | |||
| 26 | The line is returned in two pieces. | ||
| 27 | The first piece is stored in | ||
| 28 | .IR sa . | ||
| 29 | The second piece is | ||
| 30 | .IR cont , | ||
| 31 | a pointer to | ||
| 32 | .I clen | ||
| 33 | characters inside the | ||
| 34 | .I ss | ||
| 35 | buffer. | ||
| 36 | The second piece must be copied somewhere else | ||
| 37 | before | ||
| 38 | .I ss | ||
| 39 | is used again. | ||
| 40 | |||
| 41 | If | ||
| 42 | .B getln2 | ||
| 43 | sees end-of-input before it sees | ||
| 44 | .IR sep , | ||
| 45 | it sets | ||
| 46 | .I clen | ||
| 47 | to 0 and does not set | ||
| 48 | .IR cont . | ||
| 49 | It puts the partial line into | ||
| 50 | .IR sa . | ||
| 51 | |||
| 52 | .B getln2 | ||
| 53 | normally returns 0. | ||
| 54 | If it runs out of memory, | ||
| 55 | or encounters an error from | ||
| 56 | .IR ss , | ||
| 57 | it returns -1, | ||
| 58 | setting | ||
| 59 | .B errno | ||
| 60 | appropriately. | ||
