ABSPATH(3) Schily's LIBRARY FUNCTIONS ABSPATH(3)
NAME
abspath(), absnpath(), absfpath() - Expands a relative pathname to a
full (absolute) pathname
SYNOPSIS
#include <schily/schily.h>
char *
abspath(relp, absp, asize)
const char *relp;
char *absp;
size_t asize;
char *
absnpath(relp, absp, asize)
const char *relp;
char *absp;
size_t asize;
char *
absfpath(relp, absp, asize, flags)
const char *relp;
char *absp;
size_t asize;
int flags;
DESCRIPTION
abspath() takes a relative path name and converts it into an absolute
path name. relp is relative path name that is used as the input. absp
is the buffer used for the result of the conversion. asize is the size
of the result buffer.
absnpath() behaves like abspath() exept that the file does not need to
exist.
absfpath() takes an additional flags parameter from the set of flags
from resolvefpath() to control the behavior.
RETURN VALUE
On successful completion, abspath(), absnpath() and absfpath() return a
pointer to the resolved name absp. Otherwise, a null pointer is
returned and errno is set to indicate the error, and the contents of
the buffer pointed to by absp is left in an indeterminate state.
ERRORS
ERANGE The path does not fit into the suplied buffer.
EFAULT A null pointer was suplied as pathname.
EINVAL An empty relative path was supplied.
