WORDEXP.H 3HEAD "Sep 10, 2004"
NAME
wordexp.h, wordexp - word-expansion types
SYNOPSIS

#include <wordexp.h>
DESCRIPTION

The <wordexp.h> header defines the structures and symbolic constants used by the wordexp() and wordfree() functions. See wordexp(3C).

The structure type wordexp_t contains the following members:

size_t we_wordc /* count of words matched by words */
char **we_wordv /* pointer to list of expanded words */
size_t we_offs /* slots to reserve at the beginning
 of we_wordv */

The flags argument to the wordexp() function is the bitwise-inclusive OR of the following flags: WRDE_APPEND

Append words to those previously generated.

WRDE_DOOFFS

Number of null pointers to prepend to we_wordv.

WRDE_NOCMD

Fail if command substitution is requested.

WRDE_REUSE

The pwordexp argument was passed to a previous successful call to wordexp(), and has not been passed to wordfree(). The result is the same as if the application had called wordfree() and then called wordexp() without WRDE_REUSE.

WRDE_SHOWERR

Do not redirect stderr to /dev/null.

WRDE_UNDEF

Report error on an attempt to expand an undefined shell variable.

The following constants are defined as error return values: WRDE_BADCHAR

One of the unquoted characters\(em<newline>, '|', '&', ';', '<', '>', '(', ')', '{', '}'\(emappears in words in an inappropriate context.

WRDE_BADVAL

Reference to undefined shell variable when WRDE_UNDEF is set in flags.

WRDE_CMDSUB

Command substitution requested when WRDE_NOCMD was set in flags.

WRDE_NOSPACE

Attempt to allocate memory failed.

WRDE_NOSYS

Reserved.

WRDE_SYNTAX

Shell syntax error, such as unbalanced parentheses or unterminated string.

The <wordexp.h> header defines the following type: size_t

As described in <stddef.h>.
