- Abstract
Replace a marker with an integer.

VARIABLE I/O DESCRIPTION
-------- --- --------------------------------------------------
in I Input string.
marker I Marker to be replaced.
value I Replacement value.
lenout I Available space in output string.
out O Output string.
MAXLI P Maximum length of an integer.
- Detailed_Input
in is an arbitrary character string.
marker is an arbitrary character string. The first occurrence
of marker in the input string is to be replaced by value.
Leading and trailing blanks in marker are NOT significant.
In particular, no substitution is performed if marker
is blank.
value is an arbitrary integer.
lenout is the allowed length of the output string. This length
must large enough to hold the output string plus the
terminator. If the output string is expected to have x
characters, lenout should be at least x + 1.
- Detailed_Output
out is the string obtained by substituting the text
representation of value for the first occurrence
of marker in the input string.
out and in must be identical or disjoint.
- Parameters
MAXLI is the maximum expected length of the text
representation of an integer. 11 characters are
sufficient to hold any integer whose absolute
value is less than 10 billion.
This routine assumes that the input integer
is such that its string representation contains
no more than MAXLI characters.
- Particulars
This is one of a family of related routines for inserting values
into strings. They are typically to construct messages that
are partly fixed, and partly determined at run time. For example,
a message like
"Fifty-one pictures were found in directory [USER.DATA]."
might be constructed from the fixed string
"#1 pictures were found in directory #2."
by the calls
#include "SpiceUsr.h"
.
.
.
#define LENOUT 81
.
.
.
repmct_c ( string, "#1", 51, 'c', LENOUT, string );
repmc_c ( string, "#2", "[USER.DATA]", LENOUT, string );
which substitute the cardinal text "Fifty-one" and the character
string "[USER.DATA]" for the markers "#1" and "#2" respectively.
The complete list of routines is shown below.
repmc_c ( Replace marker with character string value )
repmd_c ( Replace marker with double precision value )
repmf_c ( Replace marker with formatted d.p. value )
repmi_c ( Replace marker with integer value )
repmct_c ( Replace marker with cardinal text )
repmot_c ( Replace marker with ordinal text )
- Examples
1. Let
in == "Invalid operation value. The value was <opcode>."
Then following the call,
#include "SpiceUsr.h"
.
.
.
#define LENOUT 201
.
.
.
repmi_c ( in, "<opcode>", 5, LENOUT, outstr );
outstr contains the string:
"Invalid operation value. The value was 5."
2. Let
in == "Left endpoint exceeded right endpoint. "
"The left endpoint was: XX. The right "
"endpoint was: XX."
Then following the call,
#include "SpiceUsr.h"
.
.
.
#define LENOUT 201
.
.
.
repmi_c ( in, " XX ", 5, LENOUT, out );
out is
"Left endpoint exceeded right endpoint. The left "
"endpoint was: 5. The right endpoint was: XX."
3. Let
num == 23
chance == "fair"
score == 4.665
Then following the sequence of calls,
#include "SpiceUsr.h"
.
.
.
#define LENOUT 201
.
.
.
repmi_c ( "There are & routines that have a "
"& chance of meeting your needs."
"The maximum score was &.",
"&",
num,
LENOUT,
msg );
repmc_c ( msg, marker, chance, LENOUT, msg );
repmf_c ( msg, marker, score, 4, 'f', LENOUT, msg );
msg is
"There are 23 routines that have a fair chance of "
"meeting your needs. The maximum score was 4.665."
- Restrictions
None.
- Exceptions
1) The error SPICE(NULLPOINTER) is signaled if any of
the input or output string pointers is null.
2) If the marker string is blank or empty, this routine leaves
the input string unchanged, except that trailing blanks
will be trimmed. This case is not considered an error.
3) If the output string is too short to accommodate a terminating
null character, the error SPICE(STRINGTOOSHORT) is signaled.
4) If out does not have sufficient length to accommodate the
result of the substitution, the result will be truncated on
the right.
