◆ LoadTwmrc()

bool LoadTwmrc ( const char * filename)

Principal entry point from top-level code to parse the config file.

This tries the various permutations of config files we could load. For most possible names, we try loading $NAME.$SCREENNUM before trying $NAME. If a -f filename is given on the command line, it's passed in here, and the normal ~/.[c]twmrc* attempts are skipped if it's not found.

Parameters
filenameA filename given in the -f command-line argument (or NULL)
Returns
true/false for whether a valid config was parsed out from somewhere.

◆ ParseTwmrc()

int ParseTwmrc ( const char * filename)
static

Try parsing a file as a ctwmrc.

Parameters
filenameThe filename to try opening and parsing.
Returns
-1,0,1. 0/1 should be treated as false/true for whether parsing the file succeeded. -1 means the file couldn't be opened.
