NAME

allread, allreadv - read requested amount of data from a file

SYNOPSIS

#include <limb/allreadwrite.h>

size_t allread(int fd, char *dst, size_t dlen)
size_t allreadv(int fd, const struct iovec *v, unsigned n)

DESCRIPTION

The allread() function will attempt to read dlen bytes from the file associated with file descriptor fd and copy them into the memory pointed by dst.

The allreadv() function is similar only placing the data into the memory described by the array v of n vectors.

RETURN VALUE

These functions return the number of bytes read, which may be less than dlen (even 0) in case of error, or if end-of-file was reached prior.
