gd_alias_target — return the target of an alias defined in a dirfile database


#include <getdata.h> const char *gd_alias_target(DIRFILE *dirfile, const char *alias_name);


The gd_alias_target() function queries a dirfile(5) database specified by dirfile and re‐ turns the target field code of the alias specified by alias_name. The dirfile argument must point to a valid DIRFILE object previously created by a call to gd_open(3). Note: the target may itself be the an alias, which will have its own target. To obtain the canonical name of the field ultimately referenced by alias_name, pass it to gd_en‐ try(3) and inspect the field member of the gd_entry_t structure returned.


Upon successful completion, gd_alias_target() returns a pointer to a read-only character string containing the name of the target of the specified alias. On error, gd_alias_tar‐ get() returns NULL and sets the dirfile error a non-zero error value. Possible error val‐ ues are: GD_E_BAD_CODE The name alias_name was not found in the dirfile. GD_E_BAD_DIRFILE The supplied dirfile was invalid. GD_E_BAD_FIELD_TYPE The entry specified by alias_name was not an alias. The dirfile error may be retrieved by calling gd_error(3). A descriptive error string for the last error encountered can be obtained from a call to gd_error_string(3).
