copylist(3G)
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
The copylist() function 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 reading the file.
USAGE
The copylist() function has an explicit 64-bit equivalent. See interface64(5).
EXAMPLES
/∗ read "file" into buf ∗/
off_t size;
char ∗buf;
buf = copylist("file", &size);
if (buf) {
for (i=0; i<size; i++)
if (buf[i])
putchar(buf[i]);
else
putchar(’\n’);
}
} else {
fprintf(stderr, "%s: Copy failed for "file".\n", argv[0]);
exit (1);
}
