Function Documentation

addexepath()

void addexepath

(

const char *

name

)

The path name is always copied to a newly allocated memory location. This path name can actually be a colon-separated list, as for initexepath().

addpath()

void addpath

(

const char *

name

)

The path name is always copied to a newly allocated memory location. This path name can actually be a colon-separated list, as for initpath(). Also environment variables (indicated by starting with '$', e.g. "$HOME") are accepted (and may expand into colon-separated list) but no mixed expansion (like "$HOME/bin").

fileopen_set_verbose()

int fileopen_set_verbose

(

int

v

)

Override at run-time what may have been initialized from the FILEOPEN_VERBOSE environment variable once.
