Tcl_Concat — concatenate a collection of strings
#include <tcl.h>
const char *
Tcl_Concat(argc, argv)
- Tcl_Size argc
(in)
- Number of strings.
- const char *const argv[] (in)
- Array of strings to concatenate. Must have argc
entries.
Tcl_Concat 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, 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.
Tcl_Concat eliminates leading and trailing white space as
it copies strings from argv to the result. If an element
of argv 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 command cleaner-looking.
The result string is dynamically allocated using Tcl_Alloc; the caller must
eventually release the space by calling Tcl_Free.
