Function Documentation

FILE* fopen_excl ( const char * file,

const char * mode

)

WIN32: Open an existing file (or create) in share-mode but deny other processes to write to the file.
On Watcom, fopen() already seems to open with SH_DENYWR internally. DOS/Watcom: simply call fopen(). Definition at line 441 of file misc.c.

DWORD get_day_num ( void )

Simplified method of getting days since 1970-01-01.
Don't use time() since it will probably link in sprintf(). We don't need accuracy. Only a reference for sock_stats(). Definition at line 198 of file misc.c.
References DWORD.

W32_FUNC void init_misc ( void )

Initialise various stuff.

Todo:
Definition at line 322 of file misc.c.

const char* MAC_address ( const void * addr )

Return hexa-decimal string for an 6/7 byte MAC-address.
Use 2 buffers in round-robin. Definition at line 935 of file misc.c.
References _pktdevclass.

int set_cbreak ( int want_brk )

Sets normal and extended BREAK mode.

want_brk 0x0000: no ^BREAK checking.

want_brk 0x0001: normal ^BREAK checks.

want_brk 0x0101: extended ^BREAK checks.

Return values:

normal BREAK state in LSB, extended BREAK state in MSB.

Definition at line 110 of file pc_cbrk.c.
References WORD.

W32_FUNC int tcp_cbreak ( int mode )

Sets our break mode.

`mode' is composed of the following flags

0x01: disallow breakouts
0x10: display a message upon ^C/^BREAK (default)

Definition at line 172 of file pc_cbrk.c.

W32_FUNC const char* wattcpVersion ( void )

Todo:
not tested
not tested
