st_lang_str(3)st_lang_str(3)NAME
st_lang_str, st_type_str, st_class_str - translate symbol table codes
to printable strings
SYNOPSIS
#include <st.h>
st_status_t st_lang_str(
st_obj_t *obj,
st_file_t file,
char *buf,
int buflen ); st_status_t st_type_str(
st_obj_t *obj,
unsigned int type,
char *buf,
int buflen ); st_status_t st_class_str(
st_obj_t *obj,
unsigned int sym_class,
char *buf,
int buflen );
PARAMETERS
Specifies an object handle, as returned by the st_obj_open() function.
Specifies an address to which these functions will copy a printable
string. Specifies the size in bytes of the memory region addressed by
the buf parameter. Specifies the handle of a file within the specified
object, for example, the handle returned by st_obj_file_start(). Spec‐
ifies the type of a symbol, as returned by st_sym_type(). Specifies
the storage class of a symbol, as returned by st_sym_class().
DESCRIPTION
These functions are used to get a printable string corresponding to an
encoded value in an object file's symbol table. The st_lang_str() func‐
tion determines the source language for a file. The st_type_str() and
st_class_str() functions translate type and class values, respectively,
to their printable form.
The buf parameter identifies an area of memory to which the
st_lang_str(), st_type_str(), and st_class_str() functions copy a
printable string. If the printable string exceeds the size specified by
the buflen parameter, these functions truncate the printable string.
RETURN VALUES
All functions indicate success by returning a value of 0 (zero). A pos‐
itive return value is an errno value from a system call. A negative
return value is a library error or informational code. The library
codes are documented in st.h.
Return parameters are set to 0 or -1 when an error occurs. Address
parameters are set to 0, and file and procedure handles are set to -1.
An exception to this is if a NULL pointer for the object or other
return parameter is input. In these cases, the return parameters will
be unchanged. A nonzero return status is the recommended method for
detecting an error return from a libst function.
