DESCRIPTION

22
23       This function is used to create a stack for use by the code compiled by
24       the JIT optimization of pcre[16|32]_study(). The arguments are a start‐
25       ing  size  for  the stack, and a maximum size to which it is allowed to
26       grow.  The  result  can  be  passed  to  the  JIT  run-time   code   by
27       pcre[16|32]_assign_jit_stack(),  or that function can set up a callback
28       for obtaining a stack. A maximum stack size of 512K  to  1M  should  be
29       more  than  enough  for  any pattern. For more details, see the pcrejit
30       page.

33       page and a description of the POSIX API in the pcreposix page.
