.SH NAME
buildCmd - build a command string from an argument vector
.SH SYNOPSIS
#include <gno/gno.h>
.sp 1
char *\fBbuildCmd\fR (char *const *\fIargv\fR);
.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.
.SH HISTORY
This routine was originally called
.BR build_cmd
and was part of the 
.BR lenviron
library written by Devin Reade for GNO v2.0.3 in April 1994.
It was incorporated into the GNO
.BR libc
as of v2.0.6.
