AUDIT_VALUE...DS_ENCODING(3) Linux Audit API AUDIT_VALUE...DS_ENCODING(3)
audit_value_needs_encoding - check a string to see if it needs
encoding
#include <libaudit.h>
int audit_value_needs_encoding(const char *str, unsigned int size);
audit_value_needs_encoding() checks size bytes from str to see if
the value must be encoded before it is logged in an audit
name/value field. Specifically, this function checks for a
double-quote, any byte in the range 0x00 through 0x20, or any byte
in the range 0x7F through 0xFF. The 0x00 through 0x20 range
includes C0 control bytes and space.
str is the byte string to check. It does not have to be NUL-
terminated and may contain embedded NUL bytes. size is the number
of bytes to check from str. If str is NULL, encoding is not
needed.
The return value if encoding is needed is 1. If not needed is 0.
audit_encode_nv_string(3), audit_encode_value(3).
