copylist(3G) — GENERAL LIBRARY FUNCTIONS
NAME
copylist − copy a file into memory
SYNOPSIS
cc [flag . . .] file . . . −lgen [library . . .]
#include <libgen.h>
char ∗copylist (const char ∗filenm, off_t ∗szptr);
DESCRIPTION
copylist copies a list of items from a file into freshly allocated memory, replacing new-lines with null characters. It expects two arguments: a pointer filenm to the name of the file to be copied, and a pointer szptr to a variable where the size of the file will be stored.
Upon success, copylist returns a pointer to the memory allocated. Otherwise it returns NULL if it has trouble finding the file, calling malloc, or opening the file.
EXAMPLES
/∗ read "file" into buf ∗/
off_t size;
char ∗buf;
buf = copylist("file", &size);
for (i = 0; i < size; i++)
if(buf[i])
putchar(buf[i]);
else
putchar(’\n’);
