LIBRARY

#include <xtend/string.h>

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);
