sasl_listmech - Retrieve a list of the supported SASL mechanisms

Synopsis

#include <sasl/sasl.h>

int sasl_listmech(sasl_conn_t *conn,
                 const char *user,
                 const char *prefix,
                 const char *sep,
                 const char *suffix,
                 const char **result,
                 unsigned *plen,
                 int *pcount);

Description

int sasl_listmech(sasl_conn_t *conn,

const char *user,

const char *prefix,

const char *sep,

const char *suffix,

const char **result,

unsigned *plen,

int *pcount);

sasl_listmech returns a string listing the SASL names of all the mechanisms available to the specified user. This is typically given to the client through a capability command or initial server response. Client applications need this list so that they know what mechanisms the server supports.

Parameters

• conn – the SASL context for this connection

• user – (optional) restricts the mechanism list to only those available to the user.

• prefix – appended to beginning of result

• sep – appended between mechanisms

• suffix – appended to end of result

• result – NULL terminated result string (allocated/freed by library)

• plen – length of result filled in by library. May be NULL

• pcount – Number of mechanisms available (filled in by library). May be NULL

Example

sasl_listmech(conn,NULL,"(",",",")",&mechlist,NULL,NULL);

may give the following string as a result:

(ANONYMOUS,KERBEROS_V4,DIGEST‐MD5)

Return Value

SASL functions should return SASL return codes. See sasl.h for a complete list. SASL_OK indicates success.
