catching errors

[Matias Atria <matias@sas.upenn.edu>]

Hi,

A short question: How can I catch errors in the PARI library from C code
so that my program does not die with
  ***   Error in the PARI system. End of program. ?
I see how this implemented by looking at the source code, but I could not
find a "public" (i.e. accessible from PARI's headers) mechanism to do it.
I don't mind using undocumented stuff, but I don't want to get in the way
of the library code.

Please enlighten me.

Many thanks,
Matias.
