st_strerror(3)st_strerror(3)NAMEst_strerror - translate a libst return code to a printable error mes‐
sage
SYNOPSIS
#include <st.h>
st_status_t st_strerror(
st_status_t errcode,
char *buf,
int buflen );
LIBRARY
Symbol Table and Object File Access Library (libst.a)
PARAMETERS
Status code returned by a function defined in the symbol table and
object file access library (libst.a). Specifies an address to which
st_strerror() will copy a printable error message string. Specifies
the size in bytes of the memory region addressed by the buf parameter.
DESCRIPTION
The st_strerror() function translates a libst error code to a printable
error message and copies that error message to the memory region
addressed by the buf parameter. If the error message exceeds the size,
in bytes, of the memory region specified by the buflen parameter,
st_strerror() will truncate the error message.
The error codes recognized and translated by the st_strerror() function
are defined in /usr/include/st.h.
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.
EXAMPLE
This code fragment illustrates how to use st_strerror() to report an
error returned by a libst routine.
#include <st.h>
...
st_obj_t *obj; st_status_t status; char *objname char
errmsg[128];
...
if (status = st_obj_open(&obj, objname, ST_RDWR)) {
st_strerror(status, errmsg, sizeof(errmsg));
fprintf(stderr, "st_obj_open failure: %s\n", errmsg);
exit(1); }
...

tion prototypes for libst.a functions
