.SH DESCRIPTION
|
||
|
|
.BR buildCmd
|
||
|
|
constructs a single string from the NULL-terminated array of arguments
|
||
|
|
.IR argv .
|
||
|
|
The string will be allocated via
|
||
|
|
.BR malloc (3),
|
||
|
|
and will consist of all of the elements of
|
||
|
|
.IR argv ,
|
||
|
|
delimited by single spaces.
|
||
|
|
.LP
|
||
|
|
If
|
||
|
|
.IR argv [0]
|
||
|
|
is NULL, a zero-length string will be constructed.
|
||
|
|
Any GS/OS prefix (numerical or otherwise) on
|
||
|
|
.IR argv [0]
|
||
|
|
will be stripped.
|
||
|
|
.SH RETURN VALUE
|
||
|
|
On success,
|
||
|
|
.BR buildCmd
|
||
|
|
returns the constructed string. On failure it returns NULL.
|
