* REXXAPI.C *
|
||
|
|
* *
|
||
|
|
* This program adds a ZIP engine directly to the REXX language. *
|
||
|
|
* The functions are: *
|
||
|
|
* UZDropFuncs -- Makes all functions in this package *
|
||
|
|
* unknown to REXX. *
|
||
|
|
* UZLoadFuncs -- Makes all functions in this package *
|
||
|
|
* known to REXX so REXX programs may *
|
||
|
|
* call them. *
|
||
|
|
* UZFileTree -- Searches for files matching a given *
|
||
|
|
* filespec, including files in *
|
||
|
|
* subdirectories. *
|
||
|
|
* UZUnZip -- Unzip command-line entry point. *
|
||
|
|
* This is functionally equivalent to *
|
||
|
|
* using Unzip as an external program. *
|
||
|
|
* UZUnZipToVar -- Unzip one file to a variable *
|
||
|
|
* UZUnZipToStem -- Unzip files to a variable array *
|
||
|
|
* UZVer -- Returns the Unzip version number *
|
||
|
|
* *
