Revision 1.3, Fri Dec 14 06:33:14 2018 UTC (5 years, 9 months ago) by schwarze
Cleanup, no functional change: Now that message handling is properly encapsulated, remove struct mparse pointers from four structs (roff, roff_man, tbl_node, eqn_node) and from the argument lists of five functions (roff_alloc, roff_man_alloc, mandoc_getarg, tbl_alloc, eqn_alloc). Except for being passed to the main program as an opaque object, it now only occurs in read.c, as it should, and not across 15 files like in the past. |
