MyISAM Merge table handler.
As with other table handlers, you'll find that the
*.c files in the
myissammrg directory have counterparts in
the myisam directory. In fact, this general
description of a myisammrg program is almost
always true: The myisammrg function checks
an argument, the myisammrg function
formulates an expression for passing to a
myisam function, the
myisammrg calls a
myisam function, the
myisammrg function returns.
These are the 22 files in the myisammrg
directory, with notes about the myisam
functions or programs they're connected with:
myrg_close.c --- mi_close.c
myrg_create.c --- mi_create.c
