Kenwood HP 9000 manual Dlgetname Routine, 252

Shared Library Management Routines

The dlopen Shared Library Management Routines

The dlgetname Routine

Retrieves the name of a load module given a load module descriptor.

Syntax

char *dlgetname(struct load_module_desc *desc, size_t desc_size,

void *(*read_tgt_mem)(void* buffer,

		unsigned long long ptr,
		size_t bufsiz,
		int ident),
	int ident_parm,
	unsigned long long load_map_parm);
	Parameters
Parameter			Description
desc		A buffer of memory allocated by the user program. The dynamic
		loader fills this in with module information.
desc_size		Size in bytes of the desc buffer.
read_tgm_mem		A pointer to a function used by dlmodinfo to retrieve needed
		information.
		If the value is NULL, the dynamic loader uses its own internal data
		structures to find the correct load module and ignore the
		ident_parm and load_map_parm parameters.
		buffer	A buffer supplied by dlmodinfo to read into.
		ptr	The virtual memory address to read from.
		bufsiz	The size of buffer in bytes.
		ident	The value of the ident_parm parameter to dlmodinfo.
ident_parm		Only used to pass the fourth parameter to read_tgt_mem.
load_map_parm		Only used when calling through read_tgt_mem. Contains the
		starting address of the load map.
