DESCRIPTION

|
<P>
|

|

This function defines, within a compile context, a function that is called
|
||
|
|
whenever <b>pcre2_compile()</b> starts to compile a parenthesized part of a
|
||
|
|
pattern. The argument to the function gives the current depth of parenthesis
|
||
|
|
nesting. The function should return zero if all is well, or non-zero to force
|
||
|
|
an error. This feature is provided so that applications can check the available
|
||
|
|
system stack space, in order to avoid running out. The result of this function
|
||
|
|
is always zero.
