Package

filename

A pathname designator.

pass-phrase

A string, or nil .

errorp

A generalized boolean.

A foreign pointer or nil .

Description

The function pem-read is an interface to the PEM_read_bio_* set of functions. See the manual entry for pem for specifications of these functions.

thing-to-read defines which function is required. pem-read concatenates thing-to-read with the string " PEM_read_bio_" to form the name of the pem function to call.

filename specifies the file to load.

If pass-phrase is non- nil , it must be a string, which is passed to the pem function. The default value of pass-phrase is nil .

If callback is non- nil , it must be a function with signature:

callback maximum-length rwflag => pass-phrase

where maximum-length is an integer, rwflag is a boolean and pass-phrase is the pass-phrase to use. The default value of callback is nil , but you cannot pass non- nil values for both pass-phrase and callback .

If it succeeds, pem-read returns a foreign pointer to the structure that was returned by the pem function. If pem-read fails, if errorp is non- nil it signals an error, otherwise it returns nil . The default value of errorp is nil .
