* Added an option to autosearch for your own installed MySQL as before. Note that default setting is to use the internal MySQL. * You can now build 32-bit even if your MySQL is x64 and vice versa. * Recommended MySQL server version for use with provided MySQL client sources is 5.1.x. * If your server version is different, let CMake autofind and use it instead (check EXTERNAL_MYSQL option) --HG-- branch : trunk

Defines: strmake()
|
|
|
|
strmake(dst,src,length) moves length characters, or until end, of src to
|
|
dst and appends a closing NUL to dst.
|
|
Note that if strlen(src) >= length then dst[length] will be set to \0
|
|
strmake() returns pointer to closing null

/*
|

'length' is the maximum length of the string; the buffer needs
|
|
to be one character larger to accomodate the terminating '\0'.
|
|
This is easy to get wrong, so we make sure we write to the
|
|
entire length of the buffer to identify incorrect buffer-sizes.
|
|
We only initialise the "unused" part of the buffer here, a) for
|
|
efficiency, and b) because dst==src is allowed, so initialising
|
|
the entire buffer would overwrite the source-string. Also, we
|
|
write a character rather than '\0' as this makes spotting these
|
|
problems in the results easier.
