Function Documentation

static int chunk_load	(	int	fd,
		off64_t	start,
		size_t	size,
		void **	ptr
	)			[static]

Load a segment of bytes from a file and return it as a new memory block.

This function fails if it cannot read exactly size bytes from the file.

Parameters:

	fd	File to read from.
	start	Position in file where to start reading.
	size	Number of bytes to read.
	ptr	Place to store pointer to newly allocated block.

Returns:

EOK on success or EIO on failure.

Definition at line 331 of file symtab.c.

int elf_core_save	(	const char *	file_name,
		as_area_info_t *	ainfo,
		unsigned int	n,
		int	phoneid
	)

Save ELF core file.

Parameters:

	file_name	Name of file to save to.
	ainfo	Array of n memory area info structures.
	n	Number of memory areas.
	phoneid	Debugging phone.

Returns:

EOK on sucess, ENOENT if file cannot be created, ENOMEM on out of memory, EIO on write error.

Definition at line 81 of file elf_core.c.

static int elf_hdr_check

(

elf_header_t *

ehdr

)

[static]

Check if ELF header is valid.

Returns:

EOK on success or negative error code.

Definition at line 288 of file symtab.c.

static int read_all	(	int	fd,
		void *	buf,
		size_t	len
	)			[static]

Read until the buffer is read in its entirety.

This function fails if it cannot read exactly len bytes from the file.

Parameters:

	fd	The file to read from.
	buf	Buffer for storing data, len bytes long.
	len	Number of bytes to read.

Returns:

EOK on error, EIO if file is short or return value from read() if reading failed.

Definition at line 370 of file symtab.c.

static int section_hdr_load	(	int	fd,
		const elf_header_t *	elf_hdr,
		int	idx,
		elf_section_header_t *	sec_hdr
	)			[static]

Load ELF section header.

Parameters:

	fd	File descriptor of ELF file.
	elf_hdr	Pointer to ELF file header in memory.
	idx	Index of section whose header to load (0 = first).
	sec_hdr	Place to store section header data.

Returns:

EOK on success or EIO if I/O failed.

Definition at line 303 of file symtab.c.

int symtab_addr_to_name	(	symtab_t *	st,
		uintptr_t	addr,
		char **	name,
		size_t *	offs
	)

Convert symbol address to name.

This function finds the symbol which starts at the highest address less than or equal to addr.

Parameters:

	st	Symbol table.
	addr	Address for lookup.
	name	Place to store pointer name of symbol, if found. This is valid while st exists.

Returns:

EOK on success or ENOENT if no matching symbol was found.

Definition at line 242 of file symtab.c.

void symtab_delete

(

symtab_t *

st

)

Delete a symtab structure.

Deallocates all resources used by the symbol table.

Definition at line 186 of file symtab.c.

int symtab_load	(	const char *	file_name,
		symtab_t **	symtab
	)

Load symbol table from an ELF file.

Parameters:

	file_name	Name of the ELF file to read from.
	symtab	Place to save pointer to new symtab structure.

Returns:

EOK on success, ENOENT if file could not be open, ENOTSUP if file parsing failed.

Definition at line 62 of file symtab.c.

int symtab_name_to_addr	(	symtab_t *	st,
		char *	name,
		uintptr_t *	addr
	)

Convert symbol name to address.

Parameters:

	st	Symbol table.
	name	Name of the symbol.
	addr	Place to store address for symbol, if found.

Returns:

EOK on success, ENOENT if no such symbol was found.

Definition at line 205 of file symtab.c.
