DESCRIPTION <\/a> <\/h2>\n

Tcl_Concat<\/b> is a utility procedure used by several of the Tcl commands. Given a collection of strings, it concatenates them together into a single string, with the original strings separated by spaces. This procedure behaves differently than Tcl_Merge<\/b>, in that the arguments are simply concatenated: no effort is made to ensure proper list structure. However, in most common usage the arguments will all be proper lists themselves; if this is true, then the result will also have proper list structure.<\/p>\n

Tcl_Concat<\/b> eliminates leading and trailing white space as it copies strings from argv<\/b> to the result. If an element of argv<\/b> consists of nothing but white space, then that string is ignored entirely. This white-space removal was added to make the output of the concat<\/b> command cleaner-looking.<\/p>\n

The result string is dynamically allocated using Tcl_Alloc<\/b>; the caller must eventually release the space by calling Tcl_Free<\/b>.<\/p>\n
