NAME
xt_str_argv_cat() - Append argv-style list to a string

LIBRARY
#include <xtend/string.h>
-lxtend

SYNOPSIS
size_t  xt_str_argv_cat(char *string, char *argv[], size_t first_arg,
size_t string_buff_size)

ARGUMENTS
string              String to which argv elements are appended
argv                Character pointer array to a list of elements
first_arg           Index of first argument to append
string_buff_size    Size of string array including null byte

DESCRIPTION
Append an argv style list of arguments to a string. This is useful for constructing a command to be passed to a shell via system() or similar methods.

RETURN VALUES
Length of string + all argv elements. If this is greater than string_buff_size, then the string has been truncated.

EXAMPLES
char    cmd[CMD_MAX + 1] = "ls",
        *argv[] = { "-l", NULL };
if ( xt_str_argv_cat(cmd, argv, 0, CMD_MAX + 1) > CMD_MAX + 1 )
    fputs("string is truncated.n", stderr);
else
    system(cmd);
