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.
