getline
GETLINE(3) Linux Programmer's Manual GETLINE(3)NAME
getline, getdelim - delimited string input
SYNOPSIS
#include <stdio.h>
ssize_t getline(char **lineptr, size_t *n, FILE *stream);
ssize_t getdelim(char **lineptr, size_t *n, int delim, FILE *stream);
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
Before glibc 2.10:
getline(), getdelim(): _GNU_SOURCE
Since glibc 2.10:
getline(), getdelim(): _POSIX_C_SOURCE >= 200809L || _XOPEN_SOURCE >= 700
DESCRIPTION
getline() reads an entire line from stream, storing the address of the buffer containing the text into *lineptr. The buffer is null-termi-
nated and includes the newline character, if one was found.
If *lineptr is NULL, then getline() will allocate a buffer for storing the line, which should be freed by the user program. (In this case,
the value in *n is ignored.)
Alternatively, before calling getline(), *lineptr can contain a pointer to a malloc(3)-allocated buffer *n bytes in size. If the buffer is
not large enough to hold the line, getline() resizes it with realloc(3), updating *lineptr and *n as necessary.
In either case, on a successful call, *lineptr and *n will be updated to reflect the buffer address and allocated size respectively.
getdelim() works like getline(), except a line delimiter other than newline can be specified as the delimiter argument. As with getline(),
a delimiter character is not added if one was not present in the input before end of file was reached.
RETURN VALUE
On success, getline() and getdelim() return the number of characters read, including the delimiter character, but not including the termi-
nating null byte. This value can be used to handle embedded null bytes in the line read.
Both functions return -1 on failure to read a line (including end-of-file condition).
ERRORS
EINVAL Bad arguments (n or lineptr is NULL, or stream is not valid).
VERSIONS
These functions are available since libc 4.6.27.
CONFORMING TO
Both getline() and getdelim() were originally GNU extensions. They were standardized in POSIX.1-2008.
EXAMPLE
#define _GNU_SOURCE
#include <stdio.h>
#include <stdlib.h>
int
main(void)
{
FILE *fp;
char *line = NULL;
size_t len = 0;
ssize_t read;
fp = fopen("/etc/motd", "r");
if (fp == NULL)
exit(EXIT_FAILURE);
while ((read = getline(&line, &len, fp)) != -1) {
printf("Retrieved line of length %zu :
", read);
printf("%s", line);
}
free(line);
exit(EXIT_SUCCESS);
}
