flux_security_aux_set(3)

SYNOPSIS

#include <flux/security/context.h>

typedef void (*flux_security_free_f)(void *arg);

int flux_security_aux_set (flux_security_t *ctx,
                           const char *name,
                           void *data,
                           flux_security_free_f destroy);

void *flux_security_aux_get (flux_security_t *ctx,
                             const char *name);

DESCRIPTION

flux_security_aux_set() attaches application-specific data to the parent object ctx. It stores data by key name, with optional destructor destroy. The destructor, if non-NULL, is called when the parent object is destroyed, or when name is overwritten by a new value. If data is NULL, the destructor for a previous value, if any is called, but no new value is stored. If name is NULL, data is stored anonymously.

flux_security_aux_get() retrieves application-specific data by name. If the data was stored anonymously, it cannot be retrieved.

RETURN VALUE

flux_security_aux_get() returns data on success, or NULL on failure, with errno set.

flux_security_aux_set() returns 0 on success, or -1 on failure, with errno set.

ERRORS

EINVAL

Some arguments were invalid.

ENOMEM

Out of memory.

ENOENT

flux_security_aux_get() could not find an entry for key.
