SSAStringCpy(3SNMP)					      SNMP Library Functions					       SSAStringCpy(3SNMP)

NAME

       SSAStringCpy, SSAStringInit, SSAStringToChar, SSAStringZero - Sun Solstice Enterprise Agent string helper functions

SYNOPSIS

       cc [ flag ... ] file ... -lssasnmp [ library .. ]
       #include <impl.h>

       void *SSAStringZero(String *string);

       int SSAStringInit(String *string, uchar_t *chars, int len, char *error_label);

       int SSAStringCpy(String *string1, String *string2, char *error_label);

       char *SSAStringToChar(String string);

DESCRIPTION

       The  SSAStringCpy()  function  makes  a deep copy of string2 to string1. This function assumes that string1 has been processed by the SSAS-
       tringZero() function. Memory is allocated inside the string1 and the contents of string2, not just the pointer, is copied to  the  string1.
       If an error is encountered,  an error message is stored in the error_label buffer.

       The  SSAStringInit() function copies the char array from chars to the string  instance with the specified length len. This function assumes
       that the string instance has been processed by the SSAStringZero() function or no memory is allocated inside the  string  instance.  If	an
       error is encountered,  an error message is stored in the error_label buffer.

       The SSAStringToChar() function returns a temporary char array buffer for printing purposes.

       The SSAStringZero() function frees the memory inside of the String instance,  but not the string object itself.

RETURN VALUES

       The  SSAStringInit() and  SSAStringCpy() functions return 0 if successful and -1 if error.
