Author:

Message:

Added str check test for error handling of psString fxns, namely stringSubstitute. Edited memory and type to include MemCheck's for string, line, and region. Added is_psType function to check for NULLs and native types first. <-will have to update all fxns next wrt to this change. Added psStringAlloc, stringFree, regionFree. Added doxygen comments.

Location:

Files:

• psRegion.c (modified) (3 diffs)
• psRegion.h (modified) (2 diffs)
