1e5118fa0cb1 This is NSS with a Cmake Buildsyste Andre Heinecke <andre.heinecke@intevation.de> parents: diff changeset	17 ** This code is built into debuggable versions of NSPR to assist in
1e5118fa0cb1 This is NSS with a Cmake Buildsyste Andre Heinecke <andre.heinecke@intevation.de> parents: diff changeset	18 ** finding misused file descriptors. Since file descritors (PRFileDesc)
1e5118fa0cb1 This is NSS with a Cmake Buildsyste Andre Heinecke <andre.heinecke@intevation.de> parents: diff changeset	19 ** are identified by a pointer to their structure, they can be the
1e5118fa0cb1 This is NSS with a Cmake Buildsyste Andre Heinecke <andre.heinecke@intevation.de> parents: diff changeset	20 ** target of dangling references. Furthermore, NSPR caches and tries
1e5118fa0cb1 This is NSS with a Cmake Buildsyste Andre Heinecke <andre.heinecke@intevation.de> parents: diff changeset	21 ** to aggressively reuse file descriptors, leading to more ambiguity.
1e5118fa0cb1 This is NSS with a Cmake Buildsyste Andre Heinecke <andre.heinecke@intevation.de> parents: diff changeset	22 ** The following code will allow a debugging client to set environment
1e5118fa0cb1 This is NSS with a Cmake Buildsyste Andre Heinecke <andre.heinecke@intevation.de> parents: diff changeset	23 ** variables and control the number of file descriptors that will be
1e5118fa0cb1 This is NSS with a Cmake Buildsyste Andre Heinecke <andre.heinecke@intevation.de> parents: diff changeset	24 ** preserved before they are recycled. The environment variables are
