FUNCTION
|
|
<<getline>>---read a line from a file
|
|
|
|
INDEX
|
|
getline
|
|
|
|
ANSI_SYNOPSIS
|
|
#include <stdio.h>
|
|
ssize_t getline(char **<[bufptr]>, size_t *<[n]>, FILE *<[fp]>);
|
|
|
|
TRAD_SYNOPSIS
|
|
#include <stdio.h>
|
|
ssize_t getline(<[bufptr]>, <[n]>, <[fp]>)
|
|
char **<[bufptr]>;
|
|
size_t *<[n]>;
|
|
FILE *<[fp]>;
|
|
|
|
DESCRIPTION
|
|
<<getline>> reads a file <[fp]> up to and possibly including the
|
|
newline character. The line is read into a buffer pointed to
|
|
by <[bufptr]> and designated with size *<[n]>. If the buffer is
|
|
not large enough, it will be dynamically grown by <<getdelim>>.
|
|
As the buffer is grown, the pointer to the size <[n]> will be
|
|
updated.
|
|
|
|
<<getline>> is equivalent to getdelim(bufptr, n, '\n', fp);
|
|
|
|
RETURNS
|
|
<<getline>> returns <<-1>> if no characters were successfully read,
|
|
otherwise, it returns the number of bytes successfully read.
|
|
at end of file, the result is nonzero.
|
|
|
|
PORTABILITY
|
|
<<getline>> is a glibc extension.
|
|
|
|
No supporting OS subroutines are directly required.
