|

*
|
||
|
|
*Purpose:
|
||
|
|
* Strcpy() copies one string onto another.
|
||
|
|
*
|
||
|
|
* Strcat() concatenates (appends) a copy of the source string to the
|
||
|
|
* end of the destination string, returning the destination string.
|
||
|
|
*
|
||
|
|
*Revision History:
|
||
|
|
* 05-31-89 JCR C version created.
|
||
|
|
* 02-27-90 GJF Fixed calling type, #include <cruntime.h>, fixed
|
||
|
|
* copyright.
|
||
|
|
* 10-01-90 GJF New-style function declarator.
|
||
|
|
* 04-01-91 SRW Add #pragma function for i386 _WIN32_ and _CRUISER_
|
||
|
|
* builds
|
||
|
|
* 04-05-91 GJF Speed up strcat() a bit (got rid of call to strcpy()).
|
||
|
|
* 09-01-93 GJF Replaced _CALLTYPE1 with __cdecl.
|
||
|
|
* 12-03-93 GJF Turn on #pragma function for all MS front-ends (esp.,
|
||
|
|
* Alpha compiler).
|
||
|
|
* 12-30-94 JCF Turn off #pragma function for MAC.
|
||
|
