Schily's LIBRARY FUNCTIONS                             ABSPATH(3)


NAME

     abspath(), absnpath(), absfpath() - Expands a relative path-
     name 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.  Oth-
     erwise, a null pointer is returned and errno is set to indi-
     cate 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.
