Subject: [PATCH] pam_inline: introduce pam_asprintf(), pam_snprintf(), and
|
||||
pam_sprintf()
|
||||
|
||||
pam_asprintf() is essentially asprintf() with the following semantic
|
||||
difference: it returns the string itself instead of its length.
|
||||
|
||||
pam_snprintf() is essentially snprintf() with the following semantic
|
||||
difference: it returns -1 in case of truncation.
|
||||
|
||||
pam_sprintf() is essentially snprintf() but with a check that the buffer
|
||||
is an array, and with an automatically calculated buffer size.
|
||||
|
||||
Use of these helpers would make error checking simpler.

||||

||||
