4.3 Error handler

The following functions may be used to register handler functions that are called by Libgcrypt in case certain error conditions occur. They may and should be registered prior to calling gcry_check_version.

Data type: gcry_handler_no_mem_t

This type is defined as: void (*gcry_handler_no_mem_t) (void *, size_t, unsigned int)

Function: void gcry_set_outofcore_handler (gcry_handler_no_mem_t func_no_mem, void *cb_data)

This function registers func_no_mem as `out-of-core handler', which means that it will be called in the case of not having enough memory available.

Data type: gcry_handler_error_t

This type is defined as: void (*gcry_handler_error_t) (void *, int, const char *)

Function: void gcry_set_fatalerror_handler (gcry_handler_error_t func_error, void *cb_data)

This function registers func_error as `error handler', which means that it will be called in error conditions.
