52
* Revision 6.35 2004/05/07 15:57:14 kans
53
* added FileCache functions for buffered read, graceful handing of Unix, Mac, and DOS line endings

56
* fix to FileGets under Darwin, was losing last character if buffer was shorter than line being read
58
* Revision 6.33 2003/11/17 17:17:57 kans
59
* changed C++ comments to C comments
61

62
* Codewarrior compiling for Win32 does not know about setmode or tempnam.
64
* Revision 6.31 2003/03/11 14:26:42 rsmith
65
* previous change to Nlm_DirCatalog made for only OS_UNIX_DARWIN, not all OS_UNIX
67
* Revision 6.30 2003/03/10 15:55:49 rsmith
68
* for OS_UNIX change implementation of DirCatalog from using popen with a ls command to using the opendir and readdir library calls.
70
* Revision 6.29 2003/02/25 15:31:03 rsmith
71
* OS_UNIX_DARWIN (Mach on Macs) uses tempnam for temporary files, not tmpnam.
73
* Revision 6.28 2002/11/06 21:23:04 ucko
74
* Don't assume MIPS is IRIX; allow Linux too.
76
* Revision 6.27 2002/10/03 17:22:29 kans
77
* for OS_MAC or OS_UNIX_DARWIN, Nlm_FileGets does fgetc loop, stopping at the first \n or \r character, and leaving a \n as the last character before the null byte
79
* Revision 6.26 2002/10/02 14:34:17 kans
80
* Nlm_GetOSType and Nlm_FileCreate have ifdef OS_MAC, not WIN_MAC
