#include <wordexp.h>
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.
Number of null pointers to prepend to we_wordv.
Fail if command substitution is requested.
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.
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.
Reference to undefined shell variable when WRDE_UNDEF is set in flags.
Command substitution requested when WRDE_NOCMD was set in flags.
Attempt to allocate memory failed.
Reserved.
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>.
