getln2 - read one line of data #include <getln.h> int getln2(&ss,&sa,&cont,&clen,sep); substdio ss;

stralloc sa;

char *cont;

unsigned int clen;

int sep;

getln2 reads a line of characters, terminated by a sep character, from ss . The line is returned in two pieces. The first piece is stored in sa . The second piece is cont , a pointer to clen characters inside the ss buffer. The second piece must be copied somewhere else before ss is used again. If getln2 sees end-of-input before it sees sep , it sets clen to 0 and does not set cont . It puts the partial line into sa . getln2 normally returns 0. If it runs out of memory, or encounters an error from ss , it returns -1, setting errno appropriately. stralloc(3), substdio(3), getln(3)
