/* String buffer.
Usage:
// Declare buffer and initialize it.
kmp_str_buf_t buffer;
__kmp_str_buf_init( & buffer );
// Print to buffer.
__kmp_str_buf_print(& buffer, "Error in file \"%s\" line %d\n", "foo.c", 12);
__kmp_str_buf_print(& buffer, " <%s>\n", line);
// Use buffer contents. buffer.str is a pointer to data, buffer.used is a
// number of printed characters (not including terminating zero).
write( fd, buffer.str, buffer.used );
// Free buffer.
__kmp_str_buf_free( & buffer );
// Alternatively, you can detach allocated memory from buffer:
__kmp_str_buf_detach( & buffer );
return buffer.str; // That memory should be freed eventually.
Notes:
* Buffer users may use buffer.str and buffer.used. Users should not change
any fields of buffer directly.
* buffer.str is never NULL. If buffer is empty, buffer.str points to empty
string ("").
* For performance reasons, buffer uses stack memory (buffer.bulk) first. If
stack memory is exhausted, buffer allocates memory on heap by malloc(), and
reallocates it by realloc() as amount of used memory grows.
* Buffer doubles amount of allocated memory each time it is exhausted.

programmer from buffer allocations and helps to avoid buffer overflows.
Examples:

__kmp_str_free( & str );
str = __kmp_str_format( "%s%s", orig1, orig2 ); // strcat(), doesn't care

Performance note:
This function allocates memory with malloc() calls, so do not call it from
performance-critical code. In performance-critical code consider using
kmp_str_buf_t instead, since it uses stack-allocated buffer for short
strings.
Why does this function use malloc()?
1. __kmp_allocate() returns cache-aligned memory allocated with malloc().
There are no reasons in using __kmp_allocate() for strings due to extra
overhead while cache-aligned memory is not necessary.
2. __kmp_thread_malloc() cannot be used because it requires pointer to thread
structure. We need to perform string operations during library startup
(for example, in __kmp_register_library_startup()) when no thread
structures are allocated yet.
So standard malloc() is the only available option.
