longjmp: Return to the location set by isetjmp (Fortran Library Reference)

Fortran Library Reference

`longjmp`: Return to the location set by `isetjmp`

The subroutine is called by:

call `longjmp(` `env,` `ival` `)`
`env`	`INTEGER*4`	Input	`env` is the 12-word integer array initialized by `isetjmp`. In 64-bit environments it must be declared `INTEGER*8`
`ival`	`INTEGER*4`	Output	`ival` = 0 if `isetjmp` is called explicitly `ival` ¬= 0 if `isetjmp` is called through `longjmp`

call longjmp( env, ival )

env

INTEGER*4

Input

env is the 12-word integer array initialized by isetjmp. In 64-bit environments it must be declared INTEGER*8

ival

INTEGER*4

Output

ival = 0 if isetjmp is called explicitly

ival ¬= 0 if isetjmp is called through longjmp
