NAME
aprintf, vaprintf - allocate and print formatted string
LIBRARY
gnulib - The GNU Portability Library
SYNOPSIS
#include <stdio.h>
char *aprintf(const char *restrict fmt, ...); char *vaprintf(const char *restrict fmt, va_list ap);
DESCRIPTION
The functions aprintf() and vaprintf() are analogs of sprintf(3) and vsprintf(3), except that their output is written in a space allocated as if by a call to malloc(3).
This pointer should be passed to free(3) to release the allocated storage when it is no longer needed.
RETURN VALUE
On success, these functions return a pointer to the first character of the formatted string. On error, -1 is returned, and errno is set to indicate the error.
ERRORS
See sprintf(3) and malloc(3).
