/*======================================================================
This contains most of Pine's interface to the local operating system
and hardware. Hopefully this file, os-xxx.h and makefile.xxx are the
only ones that have to be modified for most ports. Signals.c, ttyin.c,
and ttyout.c also have some dependencies. See the doc/tech-notes for
notes on porting Pine to other platforms. Here is a list of the functions
required for an implementation:
File System Access
can_access -- See if a file can be accessed
name_file_size -- Return the number of bytes in the file (by name)
fp_file_size -- Return the number of bytes in the file (by FILE *)
name_file_mtime -- Return the mtime of a file (by name)
fp_file_mtime -- Return the mtime of a file (by FILE *)
file_attrib_copy -- Copy attributes of one file to another.
is_writable_dir -- Check to see if directory exists and is writable
create_mail_dir -- Make a directory
rename_file -- change name of a file
build_path -- Put together a file system path
last_cmpnt -- Returns pointer to last component of path
expand_foldername -- Expand a folder name to full path
fnexpand -- Do filename exansion for csh style "~"
filter_filename -- Make sure file name hasn't got weird chars
cntxt_allowed -- Check whether a pathname is allowed for read/write
disk_quota -- Check the user's disk quota
read_file -- Read whole file into memory (for small files)
create_tmpfile -- Just like ANSI C tmpfile function
temp_nam -- Almost like common tempnam function
fget_pos,fset_pos -- Just like ANSI C fgetpos, fsetpos functions
Abort
coredump -- Abort running Pine dumping core if possible
System Name and Domain
hostname -- Figure out the system's host name, only
used internally in this file.
getdomainnames -- Figure out the system's domain name
canonical_name -- Returns canonical form of host name
Job Control
have_job_control -- Returns 1 if job control exists
stop_process -- What to do to stop process when it's time to stop
(only used if have_job_control returns 1)
System Error Messages (in case given one is a problem)
error_description -- Returns string describing error
System Password and Accounts
gcos_name -- Parses full name from system, only used
locally in this file so if you don't use it you
don't need it
get_user_info -- Finds in login name, full name, and homedir
local_name_lookup -- Get full name of user on system
change_passwd -- Calls system password changer
MIME utilities
mime_can_display -- Can we display this type/subtype?
exec_mailcap_cmd -- Run the mailcap command to view a type/subtype.
exec_mailcap_test_cmd -- Run mailcap test= test command.
Other stuff
