st_file_lang(3) Library Functions Manual st_file_lang(3) NAME st_file_lang, st_file_name, st_is_file_locally_stripped, st_file_proc_start, st_file_proc_count, st_file_proc_next, st_file_sym_start - Access information about the files in an object LIBRARY Symbol Table and Object File Access Library (libst.a) SYNOPSIS #include <st.h> st_status_t st_file_lang ( st_obj_t *obj, st_file_t file, unsigned int *lang ); st_status_t st_file_name ( st_obj_t *obj, st_file_t file, char **fname ); st_status_t st_is_file_locally_stripped ( st_obj_t *obj, st_file_t file, st_bool_t *stripped ); st_status_t st_file_proc_start ( st_obj_t *obj, st_file_t file, st_proc_t *pstart ); st_status_t st_file_proc_count ( st_obj_t *obj, st_file_t file, unsigned int *pcount ); st_status_t st_file_proc_next ( st_obj_t *obj, st_file_t file, st_proc_t pcur, st_proc_t *pnext ); st_status_t st_file_sym_start ( st_obj_t *obj, st_file_t file, st_sym_t *isym ); PARAMETERS Specifies an object handle, as returned by the st_obj_open function. Specifies a file handle, as returned by functions such as st_obj_file_start. Specifies an address to which st_file_lang returns the source language type of the specified file. Source language types are defined in /usr/include/symconst.h. Specifies an address to which st_file_name writes a pointer to a null-terminated string containing the filename of the specified file. The returned filename is for read- access only. A copy should be made before modifications are made to the string by the calling program. Specifies an address to which st_is_file_locally_stripped returns a Boolean value of TRUE if the specified file has been partially stripped. Specifies an address to which st_file_proc_start returns the handle of the first procedure in the specified file. Specifies an address to which st_file_proc_count writes the number of procedures within the specified file. Specifies the handle of a procedure within the specified file. st_file_proc_next uses this handle to determine pnext. Specifies an address to which st_file_proc_next returns the handle of the procedure following pcur in the specified file. If pcur equals or exceeds the number of procedures in the specified file, st_file_proc_next returns ST_E_PROC_RANGE and returns a -1 to the location to which pnext points. Specifies an ad- dress to which st_file_sym_start writes the handle of the first symbol for the specified file. DESCRIPTION All of the functions described in this reference page return informa- tion about the files in an object: Identifies the source language (for example, C++) of the specified file. Returns a pointer to a null-terminated string containing the filename of the specified file. (Note: The returned filename is for read-access only. The calling program must make any modifications to a copy of the filename string.) Checks whether the file has been par- tially stripped. A partially stripped file does not contain a complete set of symbolic information (for instance, if it was not compiled with the -g flag). Returns the handle of the first procedure in the speci- fied file. Returns the number of procedures within the specified file. Returns the handle of the procedure following pcur in the specified file. If pcur equals or exceeds the number of procedures for the spec- ified file, st_file_proc_next returns ST_E_PROC_RANGE and sets pnext to -1. Returns the handle of the first symbol for the given file handle. RETURN VALUES All functions indicate success by returning a value of 0 (zero). A positive 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 pa- rameters 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 re- turn parameter is input. In these cases, the return parameters will be unchanged. A non-zero return status is the recommended method for de- tecting an error return from a libst function.
